The article covers the most common issues and errors encountered during the installation, configuration, and operation of the BRIX On-Premises system.

## Common issues with BRIX On-Premises

1. **Issue:** Invitations to the BRIX platform and password recovery emails are not being sent.

**Solution**: in BRIX, additional configuration of the SMTP server connection parameters is required. Read more in the [Modify BRIX parameters](change-settings-enterprise.md#connect-smtp-server).

2. **Issue:** BRIX is only accessible within the corporate network. 

**Solution: **Install a reverse proxy and configure the connection to BRIX using:

- [HAProxy](haproxy-elma365.md).

- [Nginx](nginx-elma365-.md).

3. **Issue:** BRIX does not install or operates slowly.

**Solution:** On the server, check the number of cores and the presence of AVX instructions using the \[OBJECT\] command, and check for free disk space using the \[OBJECT\] command. Compare the obtained data with the minimum [system requirements](elma365-enterprise-on-premises.md).
