@amy.blais Thanks but your recommended doc did not help. However I have asked my IT team about “server uses NGINX”.
@ahmaddanial I am using Mattermost V1.23.1 on an iPhone 7 Plus with IOS 12.4.1. On my iPad I have the same V1.23.1 version of Mattermost and am running IOS 10.3.3.
It does not matter if I am using 4G or Wifi, on mobile or Ipad, the issue is the same. The grey connecting bar stays on permanently and I’m classed as Offline. I click on the 3 dots in the top right corner and click on the Offline bar to change status. I select Online and it goes Green tick for 2 seconds and then drops back to Offline again.
Sorry I am new to Mattermost and not sure I should share the server I am using as unsure of the risks of giving this information out. Hopefully you can review what I have written and provide insight should you see a common thread.
