I use a Macbook Pro which was given from my company. I have a VPN security issue. I cannot access my company server using VPN under VirginMedia broadband.
And all programs using my company account are pretty slow to load such as MS Office, Adobe, Slack and Zoom.
When I use other networks (such as my mobile network), the problem doesn't happen. So I think the issue is probably caused by VirginMedia settings. I don't use any security service add-ons.
Could you let me know how to fix it?
