Hello guys,
today i just faced out that my MailHog (mailcatcher container) does not work more properly..

The WebUi of MailHog is working but the websocket is always disconnected.. I've seen the following error in browser console:
WebSocket connection to wss://<my-domain>/api/v2/websocket failed: Unexpected response code: 400

Has anyone an idea?

What is docker/sdk version?

Hi Mike,
i have last week on Friday updated on last master... I think is 1.15

Hi Giovanni,
I'm not sure if it helps with your particular problem, but we often have issues with MailHog if there were too many emails.
In that case we have to "delete all messages" - even if you don't see any messages in the UI. After that mailhog receives mails again.

If @UKHR9UN00’s advice does not help, it would be a bug.

We changed FE architecture. However I wonder what would be wrong as the proxy pass rules are the same.

@ULYHPR789 no. It does not help
@UKHR9UN00 thank u for your tip
