When I launch the Mattermost app for iOS, “Connecting …” continues to appear under the header. On the right side, a progress circle continues to rotate.
At this time, the channel itself is updated as usual. I get a notification and a badge when a new comment is posted. However, there is a problem when touching the iOS notification center. The app crashes with a high probability.
This has continued since Mattermost was around 5.11. The app itself has also been updated twice, and is currently version 1.22.1 (build 225). I have updated Mattermost to 5.14.0.
What’s strange to me here is 5.13.0(build 5.13.2) when I look at the Mattermost version on iOS.When I access Mattermost on a PC or smartphone web browser, 5.14.0 is displayed. And I ran “Delete Documents and Data” from the iOS app settings. Then the display changed to 5.14.0.
However, this “Connecting …” will not disappear.
I reviewed the nginx configuration. In the first place, I didn’t change Mattermost’s own nginx.
Currently, this bar(Connecting…) is not displayed when accessing with a web browser on a PC or smartphone. This display is only for iOS app.
I came across a couple of articles where a user was able to have this issue ironed out after configuring the AllowCorsFrom: "*" setting in the config file based on the documentation below.
