Fixing the issues with the reverse proxy (#242)

- Fixed an issue where the reverse proxy would fail to initialize due to prot conflict and any attempt to restart would crash
- fixed an issue where we allowed routes to be created even if the reverse proxy was disabled
- fixed an issue where if the config changes in memory we would not save those changes
- added the ability to choose the port and host trough configuration or env variables
