[tor-relays] A bridge too far

Hello, Can anybody help me figure out why my bridge has stopped showing the flags fast, running and stable? Especially stable, I would love to get that flag back. I run two bridges, on two different Rasp Pi's, the one with a globe fingerprint of B08284109C72C81ACF5866A17A4CC64CE3E16499 . The other with a globe fingerprint of 1BCD3EBEFE17EEB86EEDE21D5E2DB8468E2864CF . The first bridge runs with obfs 3 & 4 on a Pi 2. It seems I lost the stable flag around the time I got obfs 4 up and running. The second bridge runs only with obfs 3 on an older Pi. I've read that the stable flag is quite handy. Any ideas about how I can get it back? Greetings, J Chase
