Whenever I have received this error it's because the max_execution_time on the server isn't high enough. I would suggest installing via the command line if that's an option -https://documentation.concrete5.org/developers/appendix/cli-commands...

I upped the max_execution_time to 600 and no joy. Does the CMS try to reach out to another server during the install because it mentions an upstream server?

It doesn't reach out anywhere (that I'm aware of) other than your MySQL server.

Hutman, I'm at a loss then. I don't have any issues with previous versions on the same server, but want to make the switch to the new version and start using it. It's rather concerning to never have this issue and then the issue starts with the new version.

I do notice that on all of my PHP versions on the dedicated server's accounts, that PHP-FPM is not set to "On" for any account. Do you think this could be causing an issue with c5 8.1.0 by chance?

To be honest I don't know what that is. Do you see any errors in the PHP Error log on the server when the install crashes? That could give an indication of what is going on.

I think it's unrelated. There was nothing in the log files that show that an error occurred, but I might be looking in the wrong place.

I have the host looking into the issue, as well. When I find out something I'll post back here so we all know, but as of right now, it's eluding all of us.

We found out what was wrong. Apparently, during an Apache update the Apache timeout was set to 60 instead of the standard 600 which is the default for the host. It was missing the last zero.

Once that was updated,we attempted the install again. It succeeded and balance was restored to the universe. I enjoy having a great host that's willing to help with problems where they really don't have to.

Thanks for your help again, Hutman.

I'm on this too!

Trying to install the latest version for two days...

I already increased the values for php.ini, but after 4 minutes the instalation fails!
Also tryed the CLI option but it returns a HTML file in 302 status!


These are my php 5.6 setting. Also tried with php7.2 and nothing different appends!

allow_url_fopen = On
allow_url_include = Off
asp_tags = Off
display_errors = On
enable_dl = Off
file_uploads = On
max_execution_time = 60000
max_input_time = 60000
max_input_vars = 60000
memory_limit = 102400M
post_max_size = 160000M
session.gc_maxlifetime = 14400
session.save_path = "/var/cpanel/php/sessions/ea-php56"
upload_max_filesize = 800M
zlib.output_compression = Off


I'm stuck on this! I'm running under a CENTOS 7.6 v80.0.22

Any help?

Sharing my experience on this... after so many tries I came out with the apace setting under WHM.

Go to "Apache Configuration > Global Configuration and there you have a Timeout Variable by default with a value of 300. Try to increase that value.

It worked for me.
