# Troubleshooting Guide

If you're experiencing unexpected behaviour or low success rates, try these initial steps.

### **Understand Our CAPTCHA Solving Process**

Familiarize yourself with how we handle CAPTCHAs by reviewing our [Handling CAPTCHA Events](https://developers.oxylabs.io/scraping-solutions/headless-browser/features/handling-captcha-events) process. This can provide insight into whether CAPTCHA challenges are the source of the issue. 

### **Try an Alternative Browser Endpoint**

Some target websites perform better with a specific browser engine. If you're using the Chrome endpoint, consider switching to the Firefox endpoint, or vice-versa:\
Chrome Endpoint: `wss://ubc.oxylabs.io`\
Firefox Endpoint: `wss://ubs.oxylabs.io`

### **Use the Country Parameter**

Specifying a country parameter in your requests can significantly increase success rates. This ensures your requests are routed through IPs from a specific geographic location, filtering out IPs from random or potentially less reliable locations.

You can specify a country for your browser session by adding the `?p_cc`  parameter to your connection URL. More information can be found in section [Geolocation targeting](https://developers.oxylabs.io/scraping-solutions/headless-browser/features/geolocation-targeting).

### **Use the Device Type Parameter** 

Experimenting with a device parameter can result in higher success rates. You can customize how the browser emulates different device types by using the `?p_device` parameter. More information can be found in [Device Type](https://developers.oxylabs.io/scraping-solutions/unblocking-browser/chrome#device-type) section. Please note this is supported only for Chrome version at the moment.
