I am just about fully SpiceCRM installed, but I have one last error that happens just after I click the ‘begin installation’ button: “Http failure response for [http://spicecrm.domain.com/backend/spiceinstaller/install:](http://spicecrm.domain.com/backend/spiceinstaller/install:) 500 Internal Server Error” I looked in all the logs I could find, nothing much telling there. apache2 -v = Apache/2.4.41 (Ubuntu) mysql - v = 8.0.25-0ubuntu0.20.04.1 (Ubuntu) php -v = v7.4.3 Tried ‘all-in-one’ but it just hung Reverted to be/fe git clones in root /var/www/html/frontend and /var/www/html/backend respective directories Thoughts? ---

You tried the all-in-one from [GitHub - spicecrm/spicecrm: SpiceCRM Master](https://github.com/spicecrm/spicecrm) master branch? ---

Yes … I cloned that to /var/www/html/spicecrm and then went to [http://domain/spicecrm](http://domain/spicecrm) to start the process. The installation did seem to start, at first with a ‘loading…’ message, then it changed to a ‘connecting…’ message, but that is as far as it went. I let it run for about 15 minutes, then reverted to the dual clone method (which did not produce results, even with minor adjustments to different parameters) ---

ok. So you can’t start the process at all. Delete browser cache and try again I just performed an installation it worked properly. ---

Thanks for the clear browser hint. Installed on fresh virtual machine, then all went well using a fresh Firefox browser session. **Next question** : what is the correct value for \*Backend URL when using the all-in-one git clone? I had cloned to a /var/www/html/spicecrm directory, then tried ‘[http://spice.domain.com/spicecrm](http://spice.domain.com/spicecrm)’ in the ‘Define Backend Connection’ dialogue. No matter which combination of DNS or IP used, I was greeted with a ’ http response code 404 returned from server’ error /var/log/php\_errors.log = empty Here are the shell commands used: cd /var/www/html git clone [GitHub - spicecrm/spicecrm: SpiceCRM Master](https://github.com/spicecrm/spicecrm) spicecrm mkdir -p config/sites chmod +w config/sites chown www-data -R spicecrm/ As per video instructions, the '/etc/apache2/sites-enabled/000-default.conf ’ file was modified as follows: Uncommented = ServerName [spice.domain.com](http://spice.domain.com) Added = \ Options Indexes FollowSymLinks Includes AllowOverride All Require all granted Allow from all … ---

If you call frontend by url being [http://domain/spicecrm](http://domain/spicecrm) then backend is [http://domain/spicecrm/api](http://domain/spicecrm/api) ---

Thanks … waiting for DNS to propagate. I can see Systems Requirements results if I use the IP address in \*Backend URL field ( ex: [http://IP/myspicecrm/api](http://IP/myspicecrm/api) ), but the System Requirements page is blank if I use the DNS name ( ex: [http://domain/myspicecrm/api](http://domain/myspicecrm/api) ). I am assuming this is a DNS issue and will wait for some period to re-try. ---

I followed manual posted here by maretval in July last year. Did a git clone as described in manual. Was able to go trough all installation screens. No issues find on system requirements page etc. Installation started and after 10 minutes I got following error: “Http failure response for [http://spicecrm.domain.com/api/install…:](http://spicecrm.domain.com/api//install...:) 500 Internal Server Error” I checked on git repository and on my server and I don’t see any install subfolder in api folder. Not sure if this can be an issue? ---

install Folder under api/ no longer exists, that is ok. you cloned master branch of public repository [GitHub - spicecrm/spicecrm: SpiceCRM Master](https://github.com/spicecrm/spicecrm) Which php version do you have? Which mysql Version? compatibility for mysql 8.0 is not achieved yet. Which database collation did you select? Some environments make problems with utfmb4. ---

Yeah, I moved to another server where mysql is 8.0. After downgrade to 5.7 all works fine.
