The Problem is unique to Firefox Users. Most of the Time it’s related to the improper Configuration of an SSL Certificate. The Error Code: "SSL_ERROR_RX_RECORD_TOO_LONG" flashes up. This basically signals that the SSL Certificate isn’t properly configured. As a Safeguard against Data Breaches and Cyber-Attacks, most Online Businesses of today don’t authorize a Connection unless there is a properly configured SSL Certificate.

Whenever new Versions of TLS are released, some systems display this Problem. The current Version is TLS 1.3, and the most recent Problems started when it was first released. A similar Problem was experienced by many Users when TLS 1.2 was first released.
