OPNsense NOOB here, very basic setup, possible DHCP issues?

[Bard]

Hello all.  I'll preface this with me being a brand new OPNsense user.  I've not found the answer to my issue on the forums here, my apologies if I've missed it.
My setup is very basic.
DSL modem in passthrough --> opnsense box (qotom 515g6)
The wan on the opnsense box is set to pppoe and authenticates, the other 5 ports are bridged as per https://docs.opnsense.org/manual/how-tos/lan_bridge.html
Ipv4 DHCP is configured to hand out 10.10.10.x address woth a 24 hour lease (default I believe).
I've also enabled opendns.
Everything functions perfectly...for a while.   It seems that after approximately 3 hours clients begin to lose their dhcp addresses, and aren't able to get a new/refreshed address.  If I put in a static IP everything is functional.  Restarting the DHCP service does not resolve the issue, but rebooting OPNsense does resolve it...for about 3 hours.
I appreciate any insight available from those with more experience.
Thanks in advance!

When the clients lose their connection, can you go to services -> DHCPv4 -> log file and post it here?

Have you tried it without opendns?  Try just barebones config.

Thanks so much for the response.  Apparently I just needed to post here for everything to work properly.  I rebooted OPNsense so I could make the above post and it's been running ever since.   If it goes down again with the same symptoms I'll post the log files.

Thanks again
