http://b-star-y.tech:8081 does not work (@ commit 1f550d67c4d662682c10358582e68c94cd2f0b6e)

[achakravarti]

When we attempt to run the HelpCovid server on http://b-star-y.tech:8081, either through make localtest0 or through ./helpcovid -D -T 2, the HelpCovid server starts and runs, but after some time aborts even when no GET or POST requests are made.

This is the output from the HelpCovid server:

Replacing the URL key in the ~/.helpcovidrc file with the IP address of http://b-star-y.tech seems to fix the problem. The HelpCovid server is running without aborting.
