Important information about the VPN service

Due to product changes at Let’s Encrypt, all certificates for VPN have to be changed. Fortunately, this only affects you if you use the SoftEther program. OpenVPN is explicitly not affected at this time.

What do I have to do now?

That’s it!

How long do I have?

It’s best to do it now, but it should be done no later than January 22, 2021.

What happens if I do nothing?

First of all: the VPN will continue to work, but from the 22nd of January you will often get certificate errors that you have to confirm and you will get messages that you should follow the above steps.
So take 5-10 minutes and follow the steps in the tutorial.
