Permission error, cache/doctrine is not writable

If setenforce is 1, I get following error:

InvalidArgumentException
The directory "/var/www/dev/public_html/GravCMS/cache/doctrine" is not writable.

However:

• ls -l
• drwsrwsr-x | apache | apache

For testing purposes I tried with following permissions:

• 0777
• 6775
• 0775

no change.

EDIT: Solution is also found at https://learn.getgrav.org/15/troubleshooting/permissions (SELinux-specific advice), somewhat missed it, assuming I was not able to connect solution to my problem. Silly me, I blame lack of coffee.

Temporary solved

Solution
Used command chcon -Rv --type=httpd_sys_rw_content_t ./ inside grav installion folder.
