Cannot access Qlik Sense outside of server

[Rehan]

We are using QV Server 12.2. QMC  is only working on the server it self. Its not working outside the server. we have a https:// URL. It was working fine until last night

Any idea what could be going wrong there ?

Kindly check if something had changed in your proxy settings.

Hey Rehan,

I am assuming this is QlikView as mentioned in your description and not Sense, as it says in the header?  

Either way: If you lost connectivity to the QMC (https://servername:4780/qmc in your case, since you mentioned you are using https) externally, but are still able to access it directly from the server, then you are likely looking at a change in firewall or proxy settings. 

Verify that all required ports are still open.
