I was using Tunnelblick, which was not very fast, but fairly reliable. Until yesterday, everything worked fine on my 2020 M1 MacBook Pro – 13.2 Ventura. The server has no internet access, so split tunneling is used. I have a VPN set up, which is being used to access a company server (intranet + network drives). but the real problem is, I have no idea what could be causing this.
I will try to describe the issue the best that I can.
