How do I get rid of the login message "Failed to connect to". I can successfully connect to the URL:

# curl -v
* Trying
* Connected to ( port 443 (#0)
. <snip>
* Connection state changed (HTTP/2 confirmed)
* Copying HTTP/2 data in stream buffer to connection buffer after upgrade: len=0
* Using Stream ID: 1 (easy handle 0x55f3654a1820)
> GET /meta-release-lts HTTP/2
. <snip>

I've not noticed any other adverse effects. I can update and upgrade without issue. The Ubuntu version is 20.04.2 LTS.
