My tezos-node is unable to connect to the gossip network and synchronize with peers. I think some restrictions are imposed in my organization's network.
I ran nmap on my organization' gateway IP Address to check which ports are open. Only port 80 is open. The rest of the ports are filtered.
What could be the reason for this ? Due to the ports being blocked or some other reason?
I have attached the screenshot of the verbose generated while running tezos-node. Kindly suggest what I should do to resolve this issue.
