If you are installing version 6.17.740 now, ensure you are downloading it from a reputable repository and that your device is not showing unexpected behavior, such as unauthorized background service notifications.

A soft reset (pressing power on the remote) does not clear memory. You need a full power cycle:
Why this works: It forces the network stack and DRM modules to reload from scratch, often clearing temporary 617 and 740 states.
Follow these solutions in order. Most users will resolve the issue by Step 3.
SSL certificates rely on accurate system time. If your TV’s clock resets (e.g., after a power outage) or is set to the wrong time zone, YouTube’s servers reject the connection with error 617. Strangely, the TV might still show the correct time on the home screen, but the internal system time differs.
A mismatched MTU (Maximum Transmission Unit) can cause error 617 on large video chunks. Set your router’s MTU to 1400 or 1450 (default is often 1500). This reduces packet fragmentation.
