Adding devices with webui doesn't work anymore

Hi, since the last update 25.1.0-112-g87eb54f72 we can not add devices to the webui anymore.

When I went into the add devices tab and selected snmpv3 some filled was already filled up with some information, usually it wasn’t before:

After I filled up the information and click add device, I got an error:

I check the SNMP option in the poller tab in the administration settings and find out this:

I’ve also tried to fill up directly here our snmpV3 Auth and then retry to add, but even with this method we get the same error message.

Also, the devices are reachable with snmpwalk command by the librenms server.

So I end up adding the device in cli with ./lnms device:add command and it worked.

Can you help us?

Only the display was updated so are you sure you have entered all the correct details?

Yes, all the details are correct and it does the same thing with snmp v2c devices that I want to add :confused:

There is problem in the SNMP transport / UDP protocol <select> in Add Device page, where <option value=‘udpselected’> should be fixed to <option value=‘udp’ selected>.
