Issue Apache don't start and 502 Bad Gateway

[Eros Bruno]

Hello, I have a problem on my VPS.
plesk shows the error "The new configuration files for the Apache web server were not created due to errors in the configuration templates"
Another error is shown to me when I run the command via ssh: "plesk repair web -server" which fails with the error: "Template_Exception: Can not restart web server:
file: /opt/psa/admin/plib/Service/Driver/Web/Server/Apache.php
line: 109
code: 0
"

Ultimately, the apache web server does not boot in any way.
Can someone help me please? I do not know what to do...

After message "The new configuration files for the Apache web server were not created due to errors in the configuration templates" should be additional details of this error. Could you please share it here?

Please try this solution - Unable to generate Apache configuration files: Template_Exception: Can not restart web server

Thanks for the reply.
I already tried that solution yesterday, but I have now re-ordered the commands as you suggest. But nothing has been solved unfortunately.

What about this one Domains' reconfiguration fails on Debian based OS: Template_Exception: Can not restart web server ?

Hi,

I have exactly the same problem. I reinstalled 3 times the VPS, always the same error with Apache as soon as we install a domain. I tried everything you propose as a solution, without success, I do not know what to do!

Regards

I am not expert but I had the problem.
I opened putty then connect to the server of the I type :

nano /etc/hosts

then add the ip of the site

example 1.1.1.1 stock.ovh (for my part at the end it's stock.ovh)

I saved the file then

 service apache2 restart

@boutiquepcland
I had seen a solution like the one you propose, but it did not work, in fact it is the template deployed by OVH is not up to date.
By installing only a distribution then install Plesk on the command line, no more problems, everything is OK.
