Disabling spdy & http/2 with repo impossible

[Jacob Baungard Hansen]

Hi,

I have installed 1.3.10 with the CentOS repos, however having several SSL related issues. I believe this very well might be the same issues which haunted Litespeed 5.0 (http://www.litespeedtech.com/support/forum/threads/solved-ls-5-0-stable-protocol-error-with-ssl-sites.11459/). 

In any case I wish to completely disable spdy and http/2, but even though I have selected "none" in the Enable SPDY/HTTP2 the webserver happily responds to spdy and http/2 requests, as tested with spdycheck.org who reports the following:

Is there anyway I can properly disable http/2 and spdy when using the repo?

Thanks

SPDY advertisement is also blank.

Hi Jacob,

I did some tests about the H2/SPDY disable settings and I did not find any real issue. Please make sure to disable the right listener and did a server restart. I also noticed that sometimes "graceful restart" may not work immediately, and then you may find H2/SPDY was not disabled, if in this case, can you wait for a while (say 30 seconds without connection) and check it again? or you can stop the server and start it.
                    bin/lswsctrl stop; bin/lswsctrl start

Thanks.
David

Hi,

We had a bit too many problems, so reverted to Apache for now. I do believe however that it was fixed after unsetting the "SSL Protocol Version" setting in the virtual host. I might do some further tests in the future, but do not have the time at the moment.
