Since mid-May we are periodically getting a redirect loop error on one of our sites. When this happens, the main URL will automatically redirect to something like https://www.oursite.com/?fbclid=IwAR2_VtpviR2-iIpIvjKLwGrzYMJE2OqyPUzJWz6IEQCXA2ytuI-IdmeWt1c&campaign=12305356211&content=497752355954&keyword&gclid=EAIaIQobChMIwPu5t4qs3AIVAQAAAB0BAAAAEAAYACAAEgJVzfD_BwE. We can fix the issue by clearing the cache, but then it will randomly happen again.
The fbclid parameter comes from inbound links from Facebook. So if someone clicks on a Facebook ad or a Facebook post that leads back to our site, they will automatically add the fbclid parameter to track that unique user.
What appears to be happening is that at random times, instead of serving users OurSite.com, ALL users are being served/redirected to some kind of cached version of OURSITE.COM which is leading to a Too Many Redirects error.
Any ideas on how can we fix this issue?
