Expiry of the Lets Encrypt certificate!

Dear designers,

Some of you have already noticed that there have been problems with our site in some browsers recently. The reason is the expiry of the Lets Encrypt certificate. This is mainly used by older browsers. Newer browsers or browsers that are regularly updated are not affected. If you are affected, please try to update your browser to the latest version.

This is not a problem that we can solve from our side.

You can find more information here:

The solution is simple: just install Firefox, a browser that has its own certificates. The problem will be solved instantly.

If your system is too old and doesn’t support the latest version, you can download an earlier version here.
