I am running OH2 for month without issues in a Docker container.
Openhab is on port 8060 and not exposed to internet so no rev proxy is in between.
If I am accessing (as usual) http://192.168.100.10:8060 I am receiving this:
Bad Message 431
reason: Request Header Fields Too Large
In openhab log I am finding this:
[WARN ] [org.eclipse.jetty.http.HttpParser ] - Header is too large 8193>8192
Try clearing the cache and restarting OH.
I did as described here:
I restarted only container, the complete Server and I rebuild the container too …
Also clear the browser cache. The actual error is I think is saying that the HTTP header that your browser is sending in your request is too large.
I deleted the firefox cache but error message still apears.
I tried it with microsoft edge … working …
I hate it!!! what es should I delete
This is caused by a ‘bad’ cookie. So clear browser cache and cookies.
It is running again. Settings function delete cookies and cache was not working. After deleting cache db it is running again!!
