Node won’t let me connect to other nodes

I am trying to connect to nodes with my node but the node keeps saying connection failed. If anyone has any ideas please help.

Almost always either an authentication problem or a port-forwarding problem. Please run auth-node-auth-check.

For a start you enabled NNX, so 50134 is now 501340; did you change the node's number in its local configuration..?

Yes I did the nnx was enabled and I added the extra number on both.

Next thing is to run the script Jason specified and post the output here, for diagnosis. I think he typoed the name; it's asl-node-auth-check
