Livechat does not work anymore on path different than /

Description:

Livechat does not work anymore on path different than /

Steps to reproduce:

1. Configure rocket on non standard path e.g. https://rocket.mycompany.com/rocket
2. Integrate the livechat on the website
3. Unable to use the rocket.chat from the website.

Expected behavior:

Use the rocket.chat from the website

Actual behavior:

In the nginx access log I'm able to see that the request starts on /rocket/livechat with code 200 and then it moves to /livechat where there is nothing and it gives 403

Server Setup Information:

• Version of Rocket.Chat Server: 3.6.3
• Operating System: Gentoo Linux
• Deployment Method: tar
• Number of Running Instances: 1
• DB Replicaset Oplog:
• NodeJS Version: 12.16.1
• MongoDB Version: 4.0.12

Client Setup Information

• Desktop App or Browser Version: chrome-85
• Operating System: Gentoo

Additional context

If I'm not mistaken it started to be broken from 3.6.1

Relevant logs:

Since there was no response in a week and we don't have the livechat working, may I ask if there is at least a way to 'downgrade' and check if it works again?

Thanks for reporting, we're looking into this issue.
Thanks.

Hi,
I updated to rocket.chat-3.8.0 and the issue is still here.

In the nginx log I still can see:

[14/Nov/2020:17:30:55 +0100] "GET /livechat/0.chunk.85c58.js HTTP/2.0" 403
[14/Nov/2020:17:30:55 +0100] "GET /livechat/polyfills.38c0c.js HTTP/2.0" 403
[14/Nov/2020:17:30:55 +0100] "GET /livechat/vendors~bundle.chunk.b4ad3.js HTTP/2.0" 403
[14/Nov/2020:17:30:55 +0100] "GET /livechat/bundle.55ca9.js HTTP/2.0" 403

And obviously the livechat does not work.
