Had happily used OpenVPN and No-IP with my R7500v2 for years. All of sudden it stopped working and I get the following errors:
2020-12-11 18:42:47 WARNING: Compression for receiving enabled. Compression has been used in the past to break encryption. Sent packets are not compressed unless "allow-compression yes" is also set. 2020-12-11 18:42:47 DEPRECATED OPTION: --cipher set to 'AES-128-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-128-CBC' to --data-ciphers or change --cipher 'AES-128-CBC' to --data-ciphers-fallback 'AES-128-CBC' to silence this warning. Enter Management Password:
Router firmware is up todate. OpenVPN client is 2.5.
