Having a hard time consistently connecting to some websites/apps.

I have Fios 5gig, had it for about a month now. I've been having problems accessing some sites, sometimes I have to try 5 or 6 times before it goes through.

Some streaming apps just randomly lose connection, and some apps on mobile don't consistently work.

However online gaming never disconnects or has packet loss. It seems like it's some issue resolving websites/services or something.

I've tried switching to both Cloudflare and Google DNS servers but the issue persisted. I've disabled IPV6, I've switch the cable from the fiber modem to the router with a brand new cable. I've tried disabling unnecessary security features in the router, still no long.

Help please.
