5GEE Router - ERR_SSL_VERSION_OR_CIPHER_MISMATCH

[5GEERouter]

Getting an 'ERR_SSL_VERSION_OR_CIPHER_MISMATCH' message when launching facebook.com (Windows 10 PC, screen grab below).  Does not occur on all sites, for instance ebay and bbc news work fine.  Problem started a couple of months ago and I have covered off common issues, i.e. checked TLS1.3 is enabled, cleared SSL state, rebooted router.  Issue would appear to be on the EE5G router side as no such issue when using mobile phone (Apple 13) as a wifi hotspot for Windows PC (phone also on EE 5G network).

Any pointers gratefully received - Thankyou

Hi @5GEERouter 

Welcome to the community.

Is the content lock enabled in your EE Online account? My thoughts are that this could be blocking the connection.

Hi Chris, many thanks for advice.  I did not consider content lock settings as I've been using the router for a year now (same SIM and no changes from my end) and facebook access only started to fail a couple of months ago.  Looks like EE have changed something on their side such that I now need to change my local settings.  Will give it try - Thankyou.

May be WPA Mode: WPA or WPA2 or both. WPA2 is most secure.
