I’ve set up the rak7246G into TTN and its status is connected but no packets are received. Node are close to the gateway, and it is checked with TTN through another gateway.
Check the log on the gateway itself, probably something like sudo tail -f /var/log/syslog
Is the packet forwarder running?
Is it receiving packets?
Is it actually pointed at TTN servers? Is it getting push acks?
Are you sure your RAK7246 is for the frequency band applicable in your area, and that the global_config.json holds the appropriate channel definitions used by TTN in your particular regional bandplan?
Here is an extract from the logs:

You haven’t received any node transmissions during this period, which is not very unusual as nodes should transmit infrequently. You may have to study the logs for a longer period of time, or you may have a problem with your node, or one or both of your node or gateway may not be correct for your region of the world.
PULL_DATA sent: 3 (100.00% acknowledged)
This at least is good news; the gateway is in bidirectional communication with whatever network server you pointed it at
I think that lora module (gateway) doesn’t work properly. I’ve got another gateway and i can receive messages through that one.
This is the packet received by another gateway form ttgo node. (frequency configuration is 868100000, i don’t know why is shown 868099975 in ttn payload.)

Given that you show such a short piece of log, you almost certainly weren’t watching when your node actually transmitted, so you need to watch continuously while waiting to see that the other gateway got a packet. Also make sure your antenna is connected, etc.
Of course your gateway could also be misconfigured with the wrong contents in the applicable global_config.json for your regional bandplan.
During startup of the packet forwarder, the channel frequencies monitored will be printed to the log; compare them to the (rounded off) channel your node actually transmitted on.
It was a short extract of the log but i was watching for a long time and it’s the same…
During the same time i’m sure that node worked fine (i recived messages throught another gate).
I’ve re-installed firmware, checked conections, etc.
This is the log at the beggining, the channel frequencies are ok (as far as i know), EU range.
