AT1 (Vienna, Austria) has changed IP. The default OpenVPN and SoftEther configs of AT1 (domain name based) were not changed, the configs based on IP were changed. Update it please.
SE1 has been replaced by AT1 (Austria, Vienna). And now we have chains single-rsa-AT1, single-ecc-AT1, double-rsa-AT1-de2, double-ecc-AT1-de2, double-rsa-de2-AT1, double-ecc-de2-AT1 instead of single-rsa-se1, single-ecc-se1, double-rsa-se1-de2 etc. Download the new configs and delete the old ones.
