 ## Troubleshooting
 
+### "Error 200" or Login Issues
+
+This typically means you installed with the wrong pyMC_Repeater branch. The login functionality is only available in the `feat/dmg` branch.
+
+**To fix:**
+```bash
+cd pymc_console
+sudo bash manage.sh upgrade
+```
+
+Select **Full pyMC Stack** upgrade and choose the `feat/dmg` branch.
+
+> **Note:** When entering the branch name, use `feat/dmg` (not just `dmg`).
