So for testing reasons I turned off the firewall on:
- network-server
- application-server
- gateway-bridge
UPDATE: When all firewalls are down the gateway is shown as online in the application server. So it is clear that some port is blocking. However, devices do still not join because the network server do not send any Join accept
UPDATE 2: So the reason why my device is not joining is:
time="2020-11-03T17:46:14+01:00" level=error msg="join-server returned error: http post error: Post \"http://network-server:8003\": dial tcp 192.x.x.x:8003: connect: connection refused" dev_eui=0018b2000000231a type=OTAA
This is quite interesting as I turned off all firewalls so their should not be any issue. The join server is part of the network server right ? It is not a separate component that needs to be installed?
UPDATE 3: So I can confirm that if I am on the server and try to do:
telnet 127.0.0.1 8003
I get a connection refused although the network server is running. In a different thread I found a suggestion saying that changing
[join_server]
resolve_join_eui=false
resolve_domain_suffix=".joineuis.lora-alliance.org"
[join_server.default]
server="http://network-server:8003"
ca_cert=""
tls_cert=""
tls_key=""
to
[join_server]
resolve_join_eui=false
resolve_domain_suffix=".joineuis.lora-alliance.org"
[join_server.default]
server="https://network-server:8003"
ca_cert=""
tls_cert=""
tls_key=""
in the network server configuration would do the trick but I cannot confirm this. Someone already had this issue and managed to solve it ?
but this did not change anything. Someone having an idea where the issue could be ?
