I'm very new with network, so forgive me if I ask dumb questions or if my vocabulary is bad
I'm trying to access an URL from a partner on a specific port. The server has a firewall which only accepts allowed IP address
The problem is that sometimes it works, sometimes not. I checked with Wireshark what the problem was and we receive a RST - ACK after a few TCP Retransmission
Before asking our partner to check their servers, I'd like to make sure that the issue is not caused by something we do wrong
What could be the cause of this error ?
Let me know if you need more informations
