Qlik QMC not opening in Local

neerajthakur — Tue, 23 Dec 2025 04:39:42 GMT

Hi,

I was trying to replace SSL Certificates with new one, while doing so I Inputted wrong thumbprint from the bundle of 3 CRT and 1 Key Provided to me, and since then QMC is not opening up, I can't replace new Thumbprint.

I have now deleted all previous certificates and reinstalled by using PFX using SSLShopper and even creating using CMD will full chain method.

I even tried changing thumbprint directly in Postgres.

netsh http show sslcert has stopped showing 443 in list completely, earlier it was showing wrong thumbprint.

Sometimes I am getting 403 error and choice to select QlikClient Certificate and New Installed Certificate in Browser, even then nothing is opening up. By Default its switching to QlikClient Certificate.

Please guide me on this, need some solution ASAP. Using Qlik Enterprise

Have you tried browsing to localhost on the server.

https://localhost/qmc

Also try running netstat -aon | findstr "443", and see if anything else is using this port. In my experience the SSTP service would normally lock this port (Secure Socket Tunneling....)

Yes I have tried it even with FQDN and netstat too it doesnt list 443 and then I opened 443 in inbound outbound from Windows Firewall, still issue is same

When testing problems like this, its best to use localhost on the server, instead of DNS/friendly name, to avoid any possible routing issues.

You mentioned that you deleted previous certificates, did you delete the self-signed certs as well, as this is needed for communications between Qliksense services.

Please see below article to re-create them. Try the getting the environment up using the default self-signed certs, before going the SSL route.

I have used localhost/qmc and get this error ERR_CONNECTION_REFUSED

Have even replaced certificates using bootstrap method in attached help page

Using only qlikclient certificate I get this error : Unknown user not allowed for repository calls, missing or malformed http header: X-Qlik-User

Do the proxy and repository trace logs provide more info?
