Starting sometime last night, I’ve been having trouble with the Bluetti App connecting to my Apex 300 via the cloud. When I connect to the Apex 300 via bluetooth, and go to Settings / Network Settings, I get this:
WiFi Name: (my network)
Network Status: Connected
Network Signal: 4/5 bars
Server Status: Not Connected
"Server connection failed. Please check your network or seek assistance..."
Is there a general Bluetti server outage? If so, is there a system status page with updates?
if this is not a general outage, I’d like to diagnose this locally. I suspect it may be a DNS problem in my network.
Can anyone tell me the DNS name of the Bluetti server(s) that are being used?
Same for my Elite 100v2, however I’m not on site and can’t “bluetooth” over to my device in the Bluetti App, but it’s powering the Internet, pinging AOK on my LAN, and has a solid WiFi connection.
I got a warning message from a HomeAssistant monitor that warns me when no AC power is being drawn for more than a half hour… Looking more closely at the “Power Energy Stats”, from the cloud my data drops to all zeros (SOC/AC/DC) at 2205MST on the 22nd, returns briefly at 0150, 0315, 0340, and lastly at 0520AM MST. So the cloud server connections are coming and going.
Starting yesterday, 05/22, my 2Apex 300, running in parallel, have been unable to communicate with the app, making the anpp totally useless to me. Each Apex 300 appears to connect normally when not in parallel mode.
Today I noticed my AC200PL ishaving the similar issue. I also noticed that for a few minutes this forum was also unreachable even though I could access other websites without issues.
My understanding is the Bluetti cloud restricts accounts to regions. Your account is registered to one region e.g. USA. Your Bluetti App knows this region (under settings Me → Country/Region) and unfortunately the app requires a connection to a Bluetti server that MUST be in the same region as your account. I wish it was not that restrictive and Bluetti changes it.
.
I think the server your Bluetti App and power station connects to is dynamically determined by network domain name resolution (DNS) as well as data returned by the Bluetti servers after checking the region set in your account.
.
I just did a packet capture of my Bluetti app (v3.0.9) when launched from a Galaxy phone.
.
DNS Query for gwpry.bluettipower.com. The answer was 139.95.6.229 which is an Alibaba server in California that is hosting for Bluetti. This first HTTPs connection was made to 139.95.6.229 on port 443 and was short lived (about 3 mins), possibly to download some content such as ads in the app.
.
DNS query for gw.bluettipower.com. The answer was CNAME gtm-apigw.bluetti.ltd. So next a DNS query was sent for gtm-apigw.bluetti.ltd with answer 8.219.99.127 (Alibaba servers in Singapore). App then makes three HTTPs (TLS v1.2) connections on TCP port 18760 to 8.219.99.127. They were very short lived, under 3 seconds. Perhaps these were to simply test connectivity before proceeding. App appears to use this address for all future HTTPs connections when using the forum, store, viewing manuals, etc.
.
Another brief connection was made to 139.95.6.229 on port 443. Through this session it appears app was directed inband (not via DNS) to make a monitoring connection to iotsg.bluettipower.com. Perhaps this is the Bluetti server returning an appropriate IOT server name for the region set in your account.
.
Final DNS Query to server returned in previous step, in my case being iotsg.bluettipower.com. The answer again was 8.219.99.127 (same address as gtm-apigw.bluetti.ltd). A TLS v1.2 connection was then made on dest port 18760 to 8.219.99.127. This connection is long lived and has been up for hours. It should stay up as long as there are no network interruptions. This must be the connection used by the app to see real-time power station status (online vs offline), statistics, etc.
.
My region is Australia, so the DNS and Bluetti infrastructure is sending me to Singapore based servers. My app is working fine, all devices show online. If I was in the USA the latter request would likely result in iotus.bluettipower.com which resolves to 47.253.45.39 hosted by Alibaba in California. Russia/France/Germany resolves to 47.254.169.86 hosted out of Alibaba Germany. China has their own server and several other Asian countries resolve to Alibaba Hong Kong.
.
So as you can see, when the app is launched there is a bit going on to connect to the Bluetti servers and it is heavily dependent on the DNS resolutions, which in turn are based on the DNS server you use. If the mobile phone (app) and power station are accessing internet through the same router they should resolve by DNS to matching server addresses and no problems.
.
My understanding is a power station can show offline (when we know WIFI and internet is working) if:
Power station connects to a server in a region that does not match the region in your account, or
Bluetti App connects to a server in a region that does not match the region in your account.
.
How could this happen ?
.
Travelling overseas or using a cell provider with a DNS issue that sends you to the wrong Bluetti servers.
You use your ISP’s DNS servers and they have stale records for Bluetti.
Your ISP has a peering issue preventing connectivity to a required Bluetti server
Account has inexplicably moved to another region and no longer matches your power stations.
App’s built in certificate is bad affecting TLS session establishment to certain servers.
App has a bug processing the DNS answers returned during launch and server selection.
App has a bug with saved account settings around selected region/country.
.
Things to try:
.
If your router is using ISP DNS, change to Cloudflare DNS server 1.1.1.1 or Google DNS 8.8.8.8
Check the Country/Region in the Bluetti App is correct. (under Me —> My Account)
Restart your mobile device, this should flush cached DNS answers.
Install the app on a spare mobile device, ideally running a different OS (Android vs IOS).
I use a Fortigate firewal router that allows me to display active udp flows and tcp connections and their uptimes. I can see my app and each of my power stations has one long running tcp conn to 8.219.99.127 (Singapore) on port 18760. In your case it should be the US server you were able to ping. Really helps to have a router that can show session level info and firewall log of session activity. My firewall can also do packet capture. Its possible your tcp conns are getting established but higher layer issue such as certificate error is preventing TLS session.
However, when I refresh the router’s data that session is gone. If I refresh a few times, I’ll see that session back in existence but it’s usually gone a second later.
My conclusion: the Apex is trying to set up a connection to iotus.bluettipower.com but the connection is either never opening, or opening but quickly being shut down.
This would be consistent with something amiss on the Bluetti Server.
@BLUETTI_CARE Are you aware of this issue? Seems to have started on May 22, 2026. Same issue even with both the app and the power station are on the same WiFi network. Only bluetooth access is working now.
@BLUETTI_CARE The Bluetti app servers are down. I tried both of my Bluetti 100 v2s and only get them on blue tooth. NO your app blaming my connections are wrong. The apps for my other different brand power stations work. It seems to be just the Bluetti app is blaming my connection that can’t connect to the servers you seemed to if of shut down? It seemed to work fine this morning 5/24/26 but ever since then the Bluetti APP has been saying its my connections fault while it isn’t? Did Bluetti shut their
severs down for some reason? I use the Bluetti App mostly as I hate having to get to the manual out every time to do some thing.
AND JUST NOW THE SERVERS ARE ON! I knew complaining about it would make Murphy’s LAW fix it!
Thankyou for checking. Yes TCP conn/session not staying up would be something failing at the application layer triggering a retry. Could be certificate issue in the app. Hard to say. Packet capture can sort of help identify if it’s failing early during the TLS key exchange. I hope @BLUETTI_CARE have escalated this their next level support.
Also in California showing the same issue on 2 elite100 v2’s and multiple android devices (app v3.0.9). Obviously something changed on the Bluetti server end. Hope it gets fixed quickly. Using Bluetooth in the interim.
I have also lost my connection to the cloud here in Maine, this all started a day or so ago. Is this actually a server side issue, and are they working on it?
Same issues here!!! I posted on the forum on the app and they replied asking for the serial number, etc. but now they won’t reply! It’s very frustrating because I’m monitor these things constantly because I have a cat in my van! I NEED THEM TO WORK!
Same issue here with an Elite 30 V2 in Brazil. I have been experiencing intermittent false positives (battery dropping to 0% in the logs for a few seconds/minutes) over the past few weeks, but since yesterday, there has been a major outage lasting several hours.
Visually, the equipment is running perfectly at 100% normal state, and local Bluetooth connection works. My home network runs on a highly stable Ubiquiti UniFi infrastructure with excellent Wi-Fi coverage, and absolutely nothing has changed on my end.
This is extremely frustrating for a premium device running as a critical UPS for my entire infrastructure. It’s clear that the Bluetti Cloud Server infrastructure is unstable.
@BLUETTI@BLUETTI_CARE — We need an official statement and a permanent fix for these cloud server connection drops. Reliable monitoring is essential for UPS equipment!
