vpn: client hangs with "openvpn: AEAD Decrypt error: cipher final failed"

Hi --I've been using the Sonic VPN service for at least a few years without any issue whatsoever. However, within the past few months or so I've noticed traffic will hang for a few moments. My quick workaround is to just bypass using the vpn for that time. I recently checked the logs of my vpn clients and found a series of one or the other message, repeating for several minutes. I did some searching and was unable to find anything conclusive. My client config hasn't changed for years + I just compared with the one offered https://ovpn.sonic.net and the options are identical.

I'm using openvpn-2.4.9-1.el7.x86_64 on CentOS Linux release 7.8.2003 (Core)

Thanks for any suggestions on this!

Have there been any changes on the VPN servers in the past 3-6 months that might be having an impact here?
