i have ubuntu18.4, nginx and php7.2 instaled on a rock pi 4 sbc.
i installed nextcloud. and opened firefox and pointed it to nextcloud.mydomain.com.
and a get a 502 bad gateway.
nginx error log:
2019/12/23 22:03:49 [crit] 5047#5047: *1 connect() to unix:/run/php/php7.3-fpm.sock failed (2: No such file or directory)…
i think the problem is php7.3-fpm because i have php7.2-fpm up and running
$ service php7.2-fpm status
● php7.2-fpm.service - The PHP 7.2 FastCGI Process Manager

how do i correct this?
i am a old geezer doing this to learn something, and i think that i need some serious hand holding here.so some help would be greatly appreciated
