The proc / sysctl limit is the global limit, you may need to add a config to the /etc/limits.d/ or /etc/security/limits.d/ folder for your specific user.

For example if your username is beargrass you could add a new file to the limits.d directory called beargrass.conf

# principal  type  item    value
beargrass    soft  nofile  655350

You can also increase the limits for an entire group by user @groupname instead of the username.
