I have the same exact issue. I think this is due to recent updates on Mikrotik routher. My devices used to work 4-5 years, not anymore..

hey guys, update from my end.. problem fixed!!! so IP mismatch issue was caused by my EOP (ethernet over power) adapters, but........ that was not a bottleneck.. my ISP(ATT) blocks NTP request on UDP 123 port, when my router runs at DMZ plus mode (PACE router), even though I have 0 firewall rules. h...

Did you get it working?
If you need help with NAT config just drop a line.

thanks for wiling to help.

filed tech support ticket, almost 2 weeks we are exchanging with emails, no results so far.
Last try was to eliminate problem causing devices, but after that, error causing IP/device changed to another device.

I had this problem too. In my case I've just added more servers and one of them finally synchronized. I've noticed that the ones added with ip don't always work, but between all of them you can get one to sync. /system ntp client set enabled=yes primary-ntp=98.175.203.200 secondary-ntp=66.219.116.1...

I tried that one too. Even though I dont see anywhere IP mismatch message, but issue is still there.

I need to sync my router time, any way. Please help us.

Check port 123 udp is not closed by your isp. I have the same problem last week from ISP. Sent from my C6833 using Tapatalk hi, how I can check?. I did some research, (even though I dont beleive, that problem on ISP side) they said use telnet to ISP to specific port, but seems it does not work well...

Are you sure that ISP is not doing something with NTP packets? It is very popular complaint at support - that NTP does not work, but almost always simply ISP is, for example, dropping such packets.

yes, because I had RB951G-2HND, on same ISP (ATT) works fine..
