Hello, I took a backup from the database and started over. Installed a new centos 8 stream server and installed a new engine version 4.5 on it. restored the database just before running engine-setup. Everything went fine but when I log on to the engine through my webinterface it still tells me this : - Keystore was tampered with, or password is incorrect I wasn't expecting this and I'm trying to figure out why now. Looking into the engine.log but nothing there that points me in the general direction. After the new install/restore I did nothing with the any certificats Can anybody point me in the right direction on how to figure this one out ? Kind regards.
