Hopefully this helps someone else.  I had this same problem with my s21 5g phone.  I saw a suggestion to switch to 3G.  Poof.  I immediately connected to my work VPN.  I was then able to switch my phone back to 5G and stay connected.  The next time I tried I left it on 5G and it worked.  I don't know the technical reason, but it seemed like it somehow couldn't pass the VPN security while on 5G, but after connecting once, it's all good.  Maybe someone else can explain better, but worked for me. 

Thank you for the information.   Please clarify whether you were making the VPN connection from your phone itself or if you were making a VPN connection from your laptop and using the phone as a hotspot.   Also, do you know what type of VPN you are using (SSL, IPSEC, IKEv2, etc.)?

At least some of the folks in this thread are trying to do the latter (connecting from a laptop)
