I have problems using https://beaufortfrancois.github.io/sandbox/physical-web/url-validator/ to validate some urls from my domain proximoati.info.
I have a big amount of urls already validated using my url shortener

but now I'm getting a "Fetch timeout" trying to validate new urls, for example https://www.proximoati.info/gp001

The workaround that I found is use another shortener service to encapsulate my short url:

but I'm unavailable to change all my beacons urls to use the google url shortener service. Seems like my domain is in a blacklist or if I reach some rate limit.
Would really appreciate your thoughts.
