Mattermost, Inc.

[SOLVED] 405 error (in some circumstances)

So, my instance of mattermost does not work on android.
And incoming webhooks seem broken too.

Although browsers, the desktop app and iOS seem to work just fine, which makes this a very odd situation.

Today I’ve stumbled upon this,

$ curl -I https://chat.digitallabs.berlin/login
HTTP/2 405

I’d assume these are related issues. Any tips?

Setup is based on this: https://docs.mattermost.com/install/docker-ebs.html

Turns out the SSL chain was not complete and Android is very picky with this.
