Hey,

my problem is with the SSL Engine of Forge: In every Init event (Pre, Init, Post) the HTTPS connection to my server fails with this exception:

    }

 

As I already mentioned before, I tried the SSL Connection methods in every other initialization event too.

The weird thing with that error is, that if I for example implement this method into a command of mine, it works flawlessly and without errors.

 

When I switch to HTTP, everything works alright again.

Testing with JDK 1.8.0_144 -> Working fine.

 

Others having the same problem with the included Java, any other solution outside of staying at HTTP?

Sounds like the trusted certificates includes with the outdated Java version shipped by the launcher reject your SSL certificate. Probably related to you using Let's Encrypt (which is fine). I don't think you have much choice except using modern Java or switching to either HTTP or a different certificate authority.

 

Edit: Yes, Let's Encrypt Authorities were added in Update 101: https://stackoverflow.com/a/34111150/3638966.

Oh, thanks for your clarification and your help.

Not sure how that should help in any way.
