I have been troubleshooting an issue across our office network where several devices experience intermittent connection drops and SSL handshake failures when attempting to browse certain remote endpoints. Our Peplink router handles dual WAN connections with load balancing, but recently traffic heading toward this specific website seems to hang during the initial handshake before eventually timing out.
Other online services load without any noticeable delay, which leads me to suspect there could be an issue with Web Blocking, DNS proxy caching, or possibly an MTU mismatch along the outbound WAN route. Has anyone encountered similar domain-specific routing stalls on recent firmware versions, and are there specific firewall or session settings that should be adjusted to clear the bottleneck?
