Hello ccepeda,
“5xx” errors family (e.g. – 503 service unavailable) are server related errors. Most probably there is something wrong on your hosting setup, so we can’t really provide much help except some guidance on where to look for.
Check your hosting if it meets the WordPress requirements:
PHP 7.2.x+
mySQL 5.6.x+
max_execution_time 60+
memory_limit 128M+
post_max_size 32M
upload_max_filesize 32M
Also, 503 error usually means that the server resources are exhausted. You may need to consult with your hosting support team in order to find what’s overloading the server.
Regards,
Dimitar
