alkismavridis commented on issue #62218:
URL: https://github.com/apache/airflow/issues/62218#issuecomment-3952161418
UPDATE:
As mentioned, I tried to increase the `execution_api -> jwt_expiration_time`
to one month.
I now get different error message (Progress!!). So the change seem to have
worked. Now the message does not speak of expired token but of "server error".
It is possible that this is due to our firewall (my long-running is and SSH
operator).

```
I will try to confirm asap that this now is an internal infrastructure issue
and not an airflow one. To test this, I used the keepalive_interval parameter
in the ssh_hook of my SSHOperator:
```python
ssh_hook=SSHHook(
ssh_conn_id="___the_connection_id___",
keepalive_interval=300
),
```
I will post news as soon as I have them. Unfortunatelly every experiment
costs 24 hours
