Could not resolve host

[vvrangler]

Hello, I have seen few times in the logs the errors below.

[2020-10-15 01:06:54.515] [ERROR]  fatal: unable to access 'https://github.com/Jopyth/MMM-Remote-Control.git/': Could not resolve host: github.com

Does anyone know if this is more likely related to local internet connectivity or something external and if there are any ways to resolve it.

Thank you kindly,

Rick

@vvrangler this is the updatenotification module trying to check to see if there are updates to modules you use

do you use pihole or somesuch?

[vvrangler]

@sdetweil No, I do not run any DNS blocking tools locally.

@vvrangler hm… they all happened at the same time… network glitch…

my internet dropped for about 1 minute yesterday… and then came back

[vvrangler]

@sdetweil Yes, I am not very confident in my Internet sometimes! I work from home and I see my connection to the office drop for a few seconds on average every day. I am also trying to rule that out as a possible cause for some mysterious lockups where the MM and RPi appear to still be running but I lose VNC connectivity and eventually have to pull the plug to reboot :-(

@vvrangler i run all my sbcs on a battery (ups) to avoid power issues and mostly wired ethernet to avoid wifi issues…

but see occasional unresponsive systems too
