I have a very weird problem. On my raspberry pi i have installed openvpn using pivpn. I've set up an tcp connection over port 80. I can connect perfectly to the pi when i'm not at work (e.g. on the road, in a coffee shop). But when I try to establish a connection at work it always fails.
I've tried different commonly used webtraffic ports and also udp but it doesn't seem to work.
However I am able to create a connection at work using private internet access, so it should be possible to create a vpn connection.
I would really like to be able to create a VPN connection to my pi. Does anyone have an idea how I can research further into this problem and fix it ? Where should i begin? What possibilities do I have ?
Thank you in advance.
The openVPN log doesn't give any detailed info. Just that it tries to connect to mu ip and port and then i get a 'server poll timeout' error.
