WebIDE won't open

Hey
I have an Gitlab 11.2.3 (06cbee3) server running in Docker behind an Apache Revers proxy,
but when I try to open Web-IDE in projects i get

Error while loading the project data. Please try again.

Do some one know how to fix this or can help me debug why this happend?

Hello,
Can you place the nginx configuration? Are you using proxy_pass?
at the moment that gitlab sends that error, what error appears in the ngnix log?

Do you mean Apache config? and if you want Gitlab Nginx config, where do I find it?
If you mean Apache, her you go

Yes, sorry, I was referring to Apache.
If you try to navigate the source code?, see the contents of a file in the project.

In my case it happened that I wanted to see a file code.java and tried to show it but it sent me that error, the fact was that when doing proxy_pass in the gitlab the path/location that was used was not found.

Possibly you can see it in the apache log.

I have the same issue with my installation.

I have not figured out the best way to debug this yet

I hope we find a clue

I have tried looking in the log files for both my apache reverse proxy and for the Gitlab Nginx and haven’t found any thing useful information on why it happens yet

a question, if you access directly in the second url, without using the reverse proxy, does it work?

it’s okay I have been too busy myself to test it anyway

I tried to eliminate the backslash of the ProxyPass but than I just got this message

The proxy server received an invalid response from an upstream server.

Can you apply the suggestion?

Hello,
I have the same issue on my docker machine.
I have a apache config:

ProxyPassReverse http://127.0.0.1:9001/
RequestHeader set X-Forwarded-Proto “https”

The
nocanon

Here is my current, NOT WORKING code…

Anyone an idea to fix?

sorry for the super late answer @Sh4d0w , can you send the complete Apache virtualhost config file?
I will have a look and test out your config when I have time to test it and see if i can find a solution for you

Hello @xaner4,

thanks for your answer.

I have installed Docker and the Gitlab inside on my productive webserver with an apache.

I can open Gitlab first with my IP and Port f.e. 1.2.3.4:9001 and second via the vhost and a subdomain like gitlab.mydomain.de.

BOTH runs into an error, so the trouble is not only the vhost. BUT the errors are different.

This is my current vhost:

ProxyPass http://127.0.0.1:9001/
ProxyPassReverse http://127.0.0.1:9001/
RequestHeader set X-Forwarded-Proto “https”

But also with the nocanon and AllowEncodedSlashes NoDecode things found in web it is not working.

Hello,

in new 13.0.0 the WebIDE works if I browse only IP:PORT

But not with my Apache Vhost. Same error and I think its only a redirect/header thing in the vhost:


ProxyPass http://127.0.0.1:9001/ nocanon
ProxyPassReverse http://127.0.0.1:9001/ nocanon
AllowEncodedSlashes NoDecode
RequestHeader set X-Forwarded-Proto “https”
