Hello,  
i can’t work on documents in nextcloud and see the folling error in the collabora logfile:

```auto
[Fri Sep 23 10:58:53.884502 2022] [proxy:error] [pid 61065] (20014)Internal error (specific information not available): [client 185.203.49.26:54243] AH01084: pass request body failed to 127.0.0.1:9980 (127.0.0.1)

```

i tried to reinstall collabora 22.05.6-1 on ubtunu 20.04 according to this howto:  
[https://www.linuxbabe.com/ubuntu/integrate-collabora-onlinenextcloud-without-docker](https://www.linuxbabe.com/ubuntu/integrate-collabora-onlinenextcloud-without-docker)  
It previously worked, but probably some server names/ip changed. I also read this:  
[https://github.com/nextcloud/richdocuments/issues/1904](https://github.com/nextcloud/richdocuments/issues/1904)  
where it is mentioned, that " `/loleaflet` has been renamed to `/browser` and `lool` to `cool`"

My collabora apache2-config:

```auto

```

I moved collabora to a different host (a root server) and it partly woks now. All rewrite rules have to point to http, not https:

```auto
ProxyPass /loleaflet http://127.0.0.1:9980/loleaflet retry=0
ProxyPassReverse /loleaflet http://127.0.0.1:9980/loleaflet
ProxyPass /browser http://127.0.0.1:9980/browser retry=0
ProxyPassReverse /browser http://127.0.0.1:9980/browser

ProxyPass /hosting/discovery http://127.0.0.1:9980/hosting/discovery retry=0
ProxyPassReverse /hosting/discovery http://127.0.0.1:9980/hosting/discovery
ProxyPassMatch "/cool/(.*)/ws$" ws://127.0.0.1:9980/cool/$1/ws nocanon
ProxyPass /cool/adminws ws://127.0.0.1:9980/cool/adminws
ProxyPass /cool http://127.0.0.1:9980/cool
ProxyPassReverse /cool http://127.0.0.1:9980/cool

```

Which makes sense, since the webserver is encrypting.  
Access control does not work, but that is a different story.
