Hi @jwilander!
After several hours, I have the following update:
- I have moved my MM to a secure SSL via Apache using this configuration, which works well.
- I no longer get any websockets errors.
- I upgraded to 3.1.0 yesterday
- I am testing using both firefox and chromium on GNU/Linux
Despite this, I still get the "spinner". Of note, the spinner only happens on new messages, not on replies.
