I'll check this right now :). It is probably outdated.

[SamTV12345]

I maybe need help how to even get the reverse proxy installed. Could you please give me a quickstart on how to install apache? I need some modules but no idea how to install or where to get them

[FredMa01]

On Debian :

apt install apache2

Activate proxy modules :
a2enmod proxy proxy_http headers proxy_wstunnel deflate

Edit virtualhost in /etc/apache2/sites-available/etherpad.conf
https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy#apache

Activate virtualhost :
a2ensite etherpad

Restart Apache2 : systemctl reload apache2

[SamTV12345]

I get Nov 06 21:22:12 ubuntu apachectl[13570]: Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration

[FredMa01]

sorry :
a2enmode rewrite

[SamTV12345]

Thanks now it works. I used the very basic script.

[SamTV12345]

It all works with the basic script for me. I copied 1 to 1. Socket IO works even websockets are succesfully connected.

[FredMa01]

If I use the very basic script, I have "Uncaught Error: Reconnect timed out".
If I delete one line and add 2 in <Location /socket.io>:

- RewriteRule /(.*) ws://localhost:9001/socket.io/$1 [P,L]
+ ProxyPass ws://localhost:9001/socket.io
+ ProxyPassReverse ws://localhost:9001/socket.io

It all works !
I saw it in this issue with the same padbootstrap-xxxxxxxxxxxxxxxxx.min.js:56 Uncaught Error :
#6693

Strange...
Perhaps something to change here : https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy#apache

[SamTV12345]

Could be. Did you have any success in experimenting with the apache config?

[FredMa01]

I think that there is a problem with the apache config on the new versions of etherpad > 2.1.0 proposed here :
https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy#apache
The line RewriteRule /(.*) ws://localhost:9001/socket.io/$1 [P,L] is blocking and needs to be deactivated
Then you have to add these 2 lines

ProxyPass ws://localhost:9001/socket.io
ProxyPassReverse ws://localhost:9001/socket.io

Hi,
same error today after git pull & docker rebuild today.
I try with and without the RewriteRule in apache config. Works many months until today.
Seems really related to apache proxy conf, with vpn and direct ip access everything works.

@SamTV12345 Can you get a look please, of course also with disabled Rewrite Rule line
