Start/Stop Container results in error: Unable to connect to remote host. HTTP status code: 400

[cvmiller]

Running lxdware v3.4 on Alpine v3.15

Noted this error after starting or stopping a container
"Unable to connect to remote host. HTTP status code: 400"

Work-around: log out of lxdware, and log back in.

The FIX is to increase the number of php-fpm7 children processes. Error log reports:

/var/log/php7 # tail error.log

Editing the /etc/php7/php-fpm.conf file and setting a value:

process.max = 16

restart php-fpm7 daemon. Clears the problem. Now it is possible to start/stop containers from lxdware.
