@itsharis Have you had a chance to take a look at the troubleshooting docs if they help https://docs.mattermost.com/deploy/mobile-troubleshoot.html#i-keep-getting-a-message-cannot-connect-to-the-server-please-check-your-server-url-and-internet-connection?

I just had a look at it. I dont see anything similar to the issue i am having. There is no proxy in my case and i am trying to get the android app to connect directly to the mattermost docker container.

Were there any errors with the SSL certificate configuration?

itsharis commented 2 years ago

I dont have SSL configured. Trying this over HTTP currently.

@itsharis Has this issue been resolved?

itsharis commented 1 year ago

I haven't had the chance to try it again using the self hosted setup. Please close if needed.

karliwalti commented 1 year ago

This issue escalated for us to the production app that has just been released on the android store. On the already existing server, messages are no longer received. Interestingly push notifications arrive.

Closing (completely, not sending to the background) and opening the app does show the new messages? Do you see a banner saying "Server unreachable" or something similar?

Same error occurs in my scenario. App cannot connect to my self hosted server. I also upgraded to the latest server version to be sure it is not sever related...... :(

Handy: Samsung Galaxy S10E App Version: 2.0.1 Mattermost Server: 7.7.1 SSL: Yes, Lets Encrypt certificate

c0deright commented 1 year ago

try connecting with the https protocol and not the http protocol

ssc85 commented 1 year ago

I have just tested it with a new Samsung Galaxy S22 - same problem. Probably this has something to do with the Lets Encrypt certificate?

n-gao commented 1 year ago

Is there any update on this issue? Several users in our team cannot use the app anymore. We use a let's encrypt certificate which is correctly setup according to the linked test site.

larkox commented 1 year ago

@n-gao You can reach me on Mattermost community and send me the link of your instance. That way I can debug what exactly is impeding the connection. Same for anyone else in the thread :smile:

n-gao commented 1 year ago

Our issues were related to ipv6, if you're on an ipv6 network and your server is only listening to ipv4, the app doesn't work. We fixed the issue by listening to ipv6 as well.

ssc85 commented 1 year ago

We also get managed to find the issue. I had a trailing / at the hostname which was not working. Unfortunately every URL change was useless unless I removed and reinstalled the app. After that it worked. Thanks to @enahum for your assistance!
