I am having an error like this when we have around 100+ users but and we will keep on refreshing to make it works again. We are currently hosting in Hostinger
What database is this? MySQL and MariaDB have a max_connections setting, which is 151 by default so 100+ users could exceed this.
You can increase this setting but if your server is managed by a hosting company you may need to contact them to get this change made. (More information on troubleshooting this).
I contacted my hosting provider and they said that they can't adjust there max connection , he also say that they set it to 500 so I think it's not about the max connection. Any solution sir I badly needed to fix it
I think the key word here is overloaded. What level of hardware does your host provide?
