Not the case here.
I see ROMON working both ways.
7.19.3 towards 7.20 and vice versa.
i had the same issue i don't have supout file because was necessary to downgrade
lots of logs like this
It’s been fixed in v7.21.beta2
Hello,
I noticed that since updating from 7.19.6 to 7.20 on my RB1100Dx4 router, which I use as a Dude server, certain devices now display 00:00:00:00 for uptime information.
This was working fine before the update, and I have checked my SNMP information and everything seems OK. It's nothing serious, but I wanted to report it.
Thank you.
The netwatch addition has been mentioned in documentation:
| Property | Description |
|---|---|
| early-failure-detection (no | yes; Default: no) | Netwatch will not wait to finish all the packets to be processed to change probe status if it is already known that host will be considered as down. |
| early-success-detection (no | yes; Default: no) | Netwatch will not wait to finish all the packets to be processed to change probe status if it is already known that host will be considered as up. |
If I understand these properly, settings allow for "better" (more "dynamic") probe scripts, without these options (or with the default no set) the netwatch needs to run all "packet-count" and thus need a fixed time given by (packet-count-1)*packet-interval+tiimeout to call if it is the case the up or down script.
ERR_QUIC_PROTOCOL_ERROR with Cloudflare websites when using DOH on first few page loads, fine with plain DNS.
Is that an error displayed by the browser (as it is a Google protocol)? Anything in the logging on the MikroTik? Different behavior from previous version of RouterOS?
I'm running a RB5009UPr router with PoE, and I have been monitoring its input voltage. However, after the latest RouterOS update for version 7.20, I noticed that the PoE voltage is now reported as 0.
[RB5009] > system/health/print
# NAME VALUE TYPE
0 poe-out-consumption 0 W
1 cpu-temperature 49 C
2 jack-voltage 0 V
3 2pin-voltage 0 V
4 poe-in-voltage 0 V
Please, does anyone know what happened?
Please generate supout.rif file and send it to support@mikrotik.com
After upgrading to ROS7.20 I have so far found 3 of my customers routers rebooting every so often by the watchdog:
router was rebooted without proper shutdown by watchdog timer
I first though that it may be an issue with the specific RB3011 models as I first only encountered it on two of those but have found one of my hAP ac2’s doing the same.
Have already submitted supout to MikroTik support.
Same issue although I have found one of my hAP ac2’s doing the same, the two other devices doing this are both RB3011’s.
Version 7.20.1 has been released:
And they splited the thread.
Who knows why…!?!!!
Update: Tested 7.20.1 on an RDS, CRS310 and RB5009, I can confirm it fixes the webfig issues I reported earlier, and the update did not assign random speeds to interface ports.
Thank you.
@erlinden i didn’t check it in previous versions, i further narrow it to: Using DoH on mikrotik and Chrome Browser and Cloudflare Websites.
Other sites work fine. Only on Chromium based browsers and on sites using cloudflare i get ERR_QUIC_PROTOCOL_ERROR Error Page.
Btw if i disable QUIC protocol in chrome then i get error connection reset.
Two days ago on a RB1100AH I did a fresh config on 7.20 after resetting the device using system/reset-configuration no-defaults=yes, today I try upgrading to 7.20.1 and the device does not have enough storage available to upgrade, 20.4 MiB free but requires 20.7MiB. I have no files stored on the device and no other packages and not a large amount of configuration.

@raymondr15 It's known that sometimes even config reset leaves "garbage" on permanent storage. In such case, netinstall is the only way out.
Another possibility: check to see which packages are installed on your device. In recent versions all packages appear as available ... and it's only too easy to actually install them all even though they're not needed ... but they do use up precious storage. If that's so, uninstall all that are not needed. You need base package (routeros), the rest are optional.
You could try Netinstall but I am not sure it is worth the hustle, RB1100AH with 64MB is too old and with limited storage for V7 so your best bet is to use it with RouterOS V6…
