No, not using that option. I've not used that in the past. Previous upgrades went smoothly without requiring a modem restart. Never have I lost upstream connectivity after an upgrade before. Rebooting the modem was either a physical power reset or via my phone to my provider to command a modem r…

After downgrading to 7.22.1 (previously used version) I've not yet lost upstream connectivity leading me to believe 7.23 has something I'll be waiting for in 7.23.1.

After upgrading to RouterOS 7.23, which introduced HTTP/2 support, I started seeing a strange issue with DoH. [Снимок экрана 2026-06-01 105200] I'm using Quad9 (https://dns11.quad9.net/dns-query) and have imported the complete certificate chain to ensure proper certificate validation. DNS resolut…

So how do you explain that it only happens on the CHR ? Take your pick on the version it's all the same! ================================================================================================== DOH MONITOR | 17:14:20 | RUNTIME: 1 min | CYCLE: 15/∞ =======================================…

I have to correct myself. The issue re-appeared after the downgrade a bit later again. Meanwhile I updated again last evening and until now it works again. It's really weird but maybe unrelated to the RouterOS version while I really have no clue.
