I don't have "PublishServerDescriptor" in my conf. Should i?

Tor logs (notices.log) look ok:

Bridge is listed as up on tor relay search:

etc.....

Sometime i see many circuits and "connectons" but right now everything is blank or at 0 (bandwith use). i just shared the connexion from my smartphone to connect to tor with my laptop (that the only thing i can do right now). i'm connected to my bridge and can browse. If i download a file ( 1GB) i can see some connections (10 outbound) in nyx and the bandwith use increases.

I don't know..despite the fact that everthing looks fine to me, i lost the fast and stable flag, sometime tor relay search says the bridge is down and in 11 days nobody connected to my bridge (ecepted me).

Thanks for running a bridge.

Check Tor's logs to make sure it is actually running and doesn't report issues. Search its hashed fingerprint on https://metrics.torproject.org/rs.html and make sure it is listed as up. Verify you did *not* set 'PublishServerDescriptor 0'. Verify you can use your bridge from outside your home. I once had a residential ISP that blocked inbound port 80 but not 443.

This actually made me realize that my home router would not properly forward ports 80 and 443 from outside. I could connect to my bridge from the LAN (even using my external IP) but not from outside. I had to change to a non-standard port, unfortunately, because apparently 80 and 443 are used by the router’s web GUI even if I disabled external access to it. That’s a shame because I understand that ports 80 and 443 are less likely to be blocked by censors.

However, it’s still not clear to me how I can confirm anyone is using the bridge.

In the nyx log you see messages like 'In the last X hours we have seen X unique clients' (I don't remember the exact wording) Those are the clients that did use your bridge.

...

When I connect to it, all I see in nyx are OUTBOUND connections and not even one inbound connection (maybe that’s by design in order to protect connecting users' privacy, I don’t know).

You are probably right. In the past you could see connecting users in nyx as inbound connections without visible IP-address. Now they are not displayed as inbound connections any more. The outbound connections that are needed for these users are still displayed.
