Version 1.68-85-g6c4596d1b
Running on Ubuntu 20.04 with Net-SNMP 5.8
Following the daily update to the version above, each time a Windows 2019 server is polled the following entry appears in the Librenms Event Log:
Unsupported SNMP Algorithm - 2
No appearances in the event log before recent update.
No updates on Windows
Unknown if it affects other versions of windows as only my Domain Controllers are monitored.
Happening here too with APC UPS & Brocade SAN Switches
Getting occasional āUnsupported SNMP Algorithm - 1ā from Cisco Catalyst 9300, Cisco 1941, Cisco 1921 & ASA 5506X & Riverbed 250H - and seemingly some APC UPS too
Started at 0025 local - which is about the time my daily update would have applied.

I have eventlog full of that messages too
Same, seems to be Cisco devices in my case as well.
I have the same issue since today.
Hello everyone ,
Same for me on all types of devices and brands including SW, FW, UPS , Routers, etc.
Cureent version is Version [1.68-85-g6c4596d1b - Thu Oct 29 2020 18:02:26 GMT+0000]

Also on Juniper since today:
Unsupported SNMP Algorithm - 1
(ubuntu 18.04 php7.4)
Same here. The latest patches must have caused this. It does not seem to be affecting any graphs but the error is annoying !
Having the same issue on all Devices, even the localhost itself 
Here is the fix for thisā¦
Which has been committed and should be publishedā¦ certainly mine appears to have stopped since applying 1.68-86-g345632267 - Fri Oct 30 2020 10:14:33 GMT+0000
Wow. That was incredibly quick!
Rain daily.sh now running 1.68-86-g345632267 and the issue is resolved.
Many thanks!
I am still seeing it with Juniper devices, will it fix it automatically or should run a command or something like that ? graphs seem ok but not sure if this is affecting something elseā¦
