I have an erlang client and seagull server. When CER is sent by erlang and its captured by seagull server. Hop-by-Hop and End-to-End identifiers are same in captured pcap file.

But erlang client keeps sending CER to seagull and seagull server does not capture them.

gen_server -> handle_info returns timeout

{diameter_event,sy_server, {closed,#Ref<0.2013523099.132382721.94052>, {'CEA',timeout}, {connect, [{connect_timer,200}, {transport_module,diameter_tcp}, {transport_config, [{reuseaddr,true}, {raddr,{127,0,0,1}}, {rport,3876}]}]}}} : State []

{diameter_event,sy_server, {reconnect,#Ref<0.2013523099.132382721.94052>, [{connect_timer,200}, {transport_module,diameter_tcp}, {transport_config, [{reuseaddr,true}, {raddr,{127,0,0,1}}, {rport,3876}]}]}} : State []

I am trying to send SLR from erlang node to seagull server, but peer-up does not working. How can I solve this problem?

Thanks in advance.

Did you capture the traffic on both sides? Maybe the CER is not reaching the server. – delephin Mar 27 '19 at 21:49
@delephin No, it reaches. `peer_up` in erlang side works. – Sachith Muhandiram Mar 28 '19 at 02:16
Did you get any kind of log from the server side? It seems like the connection is ended before the diameter server can send an answer, otherwise you'll be receiving a CEA, so I'd look in the tcp configuration. In your tcp dumps, which side is ending the connection? – delephin Mar 28 '19 at 02:55
@delephin I get `CEA` from seagull, but its when I send `SLR` from erlang to seagull server, its not received. – Sachith Muhandiram Mar 28 '19 at 03:43
Are you receiving DWR and DWA? – delephin Mar 28 '19 at 04:08
@delephin `DWR` is sent, but not answered by seagull side with `DWA` – Sachith Muhandiram Mar 28 '19 at 04:13
