problem: when I try to login my minecraft info on the cr launcher this pops up. It says An error has occurred: sun.security.validator.ValidatorException: PKIX
path validation failed:
java.security.cert.CertPathValidatorException:
timestamp check failed

then the above crash report ^^

Looks like some sort of network issue between yourself and Mojang’s login servers. I’d suggest you ask for help with it on the CR discord support channel if it persists.

Do you get the same with AC’s launcher and/or the Mojang launcher?

I don’t get this with the mojang. And I used to use the ac launcher before the merge. Now this happened when I try to use the cr. Can I use the ac launcher to get in the server?

Thanks Dags. All I had to do was re download minecraft
