Chrome Security Issue


So I have the " ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY " Error in chrome and the only way to see the website is to use Safari… I’ve already cleared my cache so its not chrome…

How can i downgrade Nginx ?? Because that seems like the only viable option

Accessing 22222 Returns Error

Fixed the issue.

For future reference.

Use this command line

nano /var/www/

Then delete http2.


Then restart Nginx. ee stack restart


@cktalon buddy I am facing the same error… There is no http2 line in my installation… Any help here would be appreciated…


When You type "nano /var/www/ "

You don’t see the below lines ??

listen 443 ssl http2; ssl on; ssl_certificate /etc/letsencrypt/live/; ssl_certificate_key /etc/letsencrypt/live/;


No… I see only ssl on; onwards…


I just resinstalled everything from scratch and now i could see http2 - Just removed that and everything is working fine. Thanks everyone…

Just to summarize: SSL ciphers was not the issue - I tried doing that - it broke the entire site. http2 was the real issue - but before 26th March, I have personally done 5 ee installs and it was never the issue.

Now the question for @admin @radhe @radhe83 is whether or not this configuration is secure or removing the http2 is simply a work around. Because this in its exact form is working on all my other sites installed before 26th March. Any answer to this will really be helpful.


Is there a proper solutions for this issue? Obviously, this workaround disables HTTP/2, which is hardly desirable. What’s the way to fix this such that HTTP/2 is supported?



Yes, just replace the old ssl cipher suite currently used in nginx.conf with the command :



@virtubox Command works like a charm - still!
