Plausible says cannot verify (although starts gathering statistics)

The "We couldn't reach your site" error is entirely unrelated to the module or its configuration, i am fairly certain.

Indeed, Plausible was collecting statistics while saying it could not reach the site— until in failing to plainly read the "couldn't reach the site" part and interpreting more generically as failing to work, i copied the script URL part of Plausible's manual setup code and put it in the API endpoint. (That first snippet the wrong one; the second snippet is correct and is what the module produces when configured properly.)

After that all data collection stopped working, it turned out. Now i have correctly put the https://plausible.io/js/script.file-downloads.hash.outbound-links.js part into the Script source and Plausible is again happily collecting statistics.

And still giving me the "We couldn't reach your site" error.

It would be nice for Plausible to have Drupal-specific instructions, or for the module to more clearly explain that the Script source should literally be taken from the <script src=, but the real problem here is Plausible.io having trouble reaching one particular site— exact same settings worked fine for another Drupal website.

Will report back with what Plausible says but 99.99% sure this is not a module problem.

I checked and the snippet this module generates looks like the one that's generated by Plausible. I'm going to close this issue, feel free to reopen in case this does turn out to be an issue with the module.
