hello, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a solution depends on the individual circumstances:
- what is the error code shown when you click on advanced on that error page?
- please also give us more information about the error by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum.
thank you!
Fehlercode: SEC_ERROR_UNKNOWN_ISSUER
