I have a On-Premise 3CX host and keeps failing on Automatic update. The update is scheduled for Saturday night but on every Monday I get a update failed log . I tried manually updating but still the same. I searched Online but no solutions. I have the check the Certiificate issues and Split DNS.I can ping the dns from inside and my 3CX App is working fine from outside All are fine. Below is the update log attached. Can someone guide me as why this fails. After this issue, The 3cx fails to login and says " General network error". I have to restart all the services to gain access Gui.
