We are getting a PR_CONNECT_RESET_ERROR when going to several sites. One such site is accuplacer.org. Things we have tried: Cleared cache and history for all time Turned off firewall, Amp (antivirus), Malwarebytes, & umbrella changed network settings on Firefox to auto detect proxy and no proxy change DNS over https off and on with CloudFare changed vlan's for the wired computers

We have found that off our wired network these sites work. We are able to reach them on our wireless network. However on the wired connections they fail with that error. Other than the NIC, AP, and Controller on the wireless side everything is the same. Anyone have any thoughts on this other than use a different browser or only use wireless computers?

Thank you Austin

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
