Running a RB5009 with multiple VLANs and DHCP servers. After upgrade to 7.17 - DHCP servers stop issuing leases. Have not encountered this on any other Tik. Have sent support a suppout. Saw another post about DHCP leases i the release thread, but a different router. “New” user, at least in terms of forums, so can’t post there
Can you please share your config? Just do be able to do a sanity check. I.e., default lease time is set to 10 min which could cause problems.
Nothing in the logging? You could add debug logging to get additional info.

Thanks for the response. Mikrotik support responded pretty promptly, apparently the issue has been identified and will be fixed in upcoming release(s).
There is nothing in the log that indicates the actual problem. I had updated twice. First time lease time was 6 hours. 2nd time 30min. Both time first and 2nd time reverting to 7.16.2 works. What's strange is initially after the update, everything seems fine, then when leases run out, devices can't get an IP.
I will note i do use multiple VLANs and dhcp servers, along with VRRP.
At this point I'm unsure if it's architecture or other feature related. 7.17 has been fine for me on gr3s, hex s, e50ug, lhg 5 acs, all with varying configs.
Will still do config export when I get a chance if you like.
