error log growing quickly superagent get timeouts

[gleep52]

My homebridge.err file is growing with constant attempt to "GET" something:

homebridge.err:

superagent GET http://ps10.pndsn.com/v2/subscribe/sub-c-blahblahblah
superagent timeout 310000ms GET http://ps10.pndsn.com/v2/subscribe/sub-c-blahblahblah

I did a whois on pndsn.com and it looks like it's Amazon?

What is this attempt to get something, and what can I do to ignore the errors if that's the only way to do it? I'd obviously like to fix the problem and not ignore - if nothing else just to understand what is happening and why.

Many thanks!
