Site cannot be reached - then loads

robinsonjas

First page load on some websites will throw the error that the "Site cannot be reached" - but within a few seconds will usually load on it's own. Sometimes if I refresh a few times it will also load. I have checked logs, disabled/removed squid/squidGuard. I verify DNS from local machine does a lookup fine on the name.
I have "Clear invalid DF bits instead of dropping the packets" checked in Adv->Firewall/NAT, also Disable Firewall Scrub is checked and I set Firewall Optimization to 'conservative' (per a few articles I've found)

pfSense is my DNS server - I have several VLANs - have tried a couple of them and exhibit same behavior on same site.
(CNN.com for example will give ERR_CONNECTION_RESET and "This site can't be reached" on GUEST wifi as well as Private wired)
I have combed thru firewall rules - but nothing stands out. And I'd assume if it is blocked it would stay blocked instead of letting traffic pass after initial load.
There does seem to be a difference in behavior from mobile on Wifi vs Wired PC tho. On mobile - cnn.com won't load at all - after several refreshes still fails. On PC wired, it auto-loaded within a couple seconds of the initial failure. Also on PC seems once it loads it's ok it seems to work after that.
