Connection Interrupted

[Volvster]

My company is using Swyx Client 12.20.18089 on a Dell Latitude E5700 laptop and when I try to logon I get an error saying 'Connection Interrupted'.

 

I've checked all the connection setting and they are correct.

 

I've even tried running a continuous ping to google 8.8.8.8, but the ping is never interrupted while I try to logon to Swyx.

 

I've exported a new Certificate to the user (several times)

 

We have around 25 devices using Swyx and I've never seen this problem before.

 

Has anyone seen this error before or know how to resolve it.
