How to add a proxy to Nstbrowser profiles

Add the proxy to a new profile

1. 1Open the Profiles menu and click Create Profile, then enter a Name.
2. 2Under Proxy, choose Custom Proxy. (Local uses your own IP, and Platform Proxy is Nstbrowser’s own proxies.)
3. 3Keep the proxy setup on Custom, the option where you type a proxy in.
4. 4Paste a line from the generator into Proxy URL: HOST:PORT:USERNAME:PASSWORD for HTTP, or socks5://HOST:SOCKS5_PORT:USERNAME:PASSWORD for SOCKS5. Nstbrowser fills in the other fields from it.
5. 5Click Check Proxy. The proxy has to pass the check before the profile can be created.
6. 6Click Create Profile to save it.

Your proxy details

After you buy a plan, open My proxies. Choose the Proxy Type (Rotating or Sticky; static IP plans skip this and show your list of IPs), the Protocol (HTTP, or SOCKS5 where your plan offers it) and a Format, then copy a line. The generator offers three formats (SOCKS5 lines always use the protocol:// format):

In the examples on this page, replace USERNAME, PASSWORD, HOST and PORT with the values from your line. SOCKS5_PORT is the port the generator shows when you pick SOCKS5.

Residential lines are either rotating (a new IP on new connections) or sticky (one IP for the time you choose). Static Datacenter, Shared ISP and Private ISP plans give you a fixed list of IPs, one per line as IP:PORT:USERNAME:PASSWORD: Private ISP IPs are yours alone, while Shared ISP IPs can also be used by other customers. Rotating Datacenter and IPv6 plans give you one endpoint, with rotating or sticky lines; IPv6 only reaches sites that have an IPv6 address.

To test a line, open https://ipinfo.io/json through it: it shows the exit IP and country. For HTTP lines you can also use the free proxy checker.

Change the proxy on an existing profile

1. 1In the Profiles table, click the … (More Actions) button in the profile’s Actions column and choose Edit.
2. 2Set the proxy the same way: Custom Proxy, paste the line into Proxy URL, check it.
3. 3Click Update Profile.

To change the proxy of several profiles at once, select them, click … above the profile list and choose Modify Proxy.

Save lines for reuse

Open Proxies in the left sidebar, click Create Group, then add proxies to the group by pasting the lines and saving. Check Proxy tests them and Clear Failed removes any that failed.

In a profile, Saved Proxies picks one stored proxy, and Saved Proxy Group picks a random proxy from the group each time the profile starts. For accounts, use Saved Proxies with one line per profile, so each account keeps its IP.

To make sticky lines, open the generator, set Proxy Type to Sticky, choose a Sticky Duration if your plan offers one, set how many lines you want in Sticky Amount, then copy or download them. Each line keeps its IP for the chosen time. The session part of a sticky username differs by plan, so always generate sticky lines instead of editing usernames by hand.

Choose the country

On residential plans, add -country- and a two-letter country code to the end of the username, for example USERNAME-country-us or USERNAME-country-gb. To combine a country with a state, a city or a sticky session, build the line in the generator, which shows only the options your plan supports. Datacenter and ISP IPs have a fixed location that you choose when you buy them.

Nstbrowser sets the profile’s language and timezone from the proxy’s IP automatically; you can change them by hand.

Tips

• Give every profile its own IP, and never share one IP between profiles. For accounts you sign into for days or weeks, use one static ISP IP per profile (Private ISP, or Shared ISP on a budget). For short sessions, use one sticky line per profile, with Sticky Amount in the generator set to the number of profiles.
• Let the profile take its timezone, language and geolocation from the proxy IP, or set them by hand to match the proxy country. A US IP with a European timezone is an easy giveaway.
• Residential sticky lines hold their IP only for the duration you pick in the generator. Static ISP IPs keep the same address for the whole plan (if the network ever replaces a Private ISP IP, your proxy list updates by itself).
• Check the IP after you save: open https://ipinfo.io/json in the profile and compare the country with the profile’s settings.

Troubleshooting

• Check Proxy fails

  Check that the proxy type matches the port (HTTP with the HTTP port, SOCKS5 with the SOCKS5 port) and re-paste the username and password.More on this error →

• Login or 407 errors

  The username or password is wrong. Copy a fresh line from the generator; don’t edit sticky usernames by hand.More on this error →

• The IP changed between sessions

  The sticky duration ended. Generate a new line for the profile, or move long-lived accounts to ISP IPs.More on this error →

• Wrong country

  Set the country in the generator or add -country-xx to the username on residential plans, then check https://ipinfo.io/json.More on this error →

• You can’t create the profile

  Nstbrowser only creates the profile once the proxy passes its check. Fix the check first; each profile’s Logs (Actions … > Logs) also show proxy errors.More on this error →
