ERR_SSL_VERSION_OR_CIPHER_MISMATCH

Maria205 · ‎16-10-2025

I keep getting this error when trying to access the company SharePoint. The SharePoint open in any other Wi-Fi but when it is connected with my home Wi-Fi gives me this error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

I called EE yesterday but the adviser didn't know how to fix it and which department in EE should I contact to help me with this.

Could you please, provide the EE phone number that can fix this error?

Hi @Maria205

Welcome to the community.

I'd recommend speaking with your company's IT helpdesk first of all, to make sure that everything is OK on that side.

If they recommend speaking with our technical support team, you can find our details on the contact us page.

@Maria205 If your laptop has the ability off an Ethernet connection on it to connect to the EE Router then check that way, and as @Christopher_G points out to you the contact us and then getting to the right Tech support if you find it is happening on both wired/wireless side of the network on your EE Router!
