Wrong SSL certificate on own https webservice

AdmiralOOM

My firewall pushes wrong ssl certificate to my https webservice through Nebula I presume, how can I deactivate that?
Or how can I port the Nebula certificate into my own webservice?

Hmm, our webservice seems to be back online without doing anything.
Is this an external force trying to affect our firewall?

I suspect you enabled SSL inspection without importing the certificate to your PC, did you?
Or you didn't close the browser after importing, so that browser hasn't detected the cert the first time.
