How to add a proxy to Octo Browser profiles

Add the proxy to a new profile

1. 1In Octo Browser, click Create Profile. (A Quick Profile starts with a direct connection, without a proxy.)
2. 2On the General tab, enter a Profile name.
3. 3Click the Proxy / VPN field. Its default, Set proxy / VPN, means no proxy. Add a new proxy; the VPN tab is only for VPN configurations.
4. 4Copy a line from the generator and paste it with Ctrl+V into the field labelled Enter IP or domain, in HOST:PORT:USERNAME:PASSWORD format. Octo also takes USERNAME:PASSWORD@HOST:PORT and the same lines with a protocol in front, such as socks5://HOST:SOCKS5_PORT:USERNAME:PASSWORD.
5. 5Make sure the protocol matches your line: HTTP for an HTTP line, or SOCKS5 with the SOCKS5 port.
6. 6Click Check proxy (newer versions label it Connection check). A green Available notice shows the proxy’s country; a red Unavailable notice means it didn’t connect.
7. 7To reuse the proxy in other profiles, tick Save to the Proxy Manager and give it a name. Then finish the profile, select it and click Start.

Note: Leave URL for IP Change empty. That field is for proxies with an IP-change link; with ZenProxy you change IP by using a new sticky line.

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. 1Close the profile first: changes apply after you save and restart it.
2. 2Click the profile’s name, or the three dots in the profile list, and select Edit profile.
3. 3Change the Proxy / VPN setting as above, then click Save.

From the profile list you can also click the profile’s connection (Direct for a profile without a proxy) and add a new proxy there. To give several profiles a proxy at once, select them and use the bulk editing menu that appears.

Save many lines in the Proxy Manager

In the Proxy Manager, click Bulk Add and paste your lines, one per line, or drag in a file. Bulk Add takes lines with the protocol in front, such as http://USERNAME:PASSWORD@HOST:PORT (the generator’s protocol://username:password@hostname:port format) or http://HOST:PORT:USERNAME:PASSWORD. Lines in another format are marked ERROR.

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.

By default, Octo sets the profile’s languages, timezone, geolocation and WebRTC from the proxy’s IP, so they match the country you chose.

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 →

• The check fails, but the line works elsewhere

  Octo’s docs say your internet provider may block its proxy checker. Try the check on another connection, or test the line with curl -v first.More on this error →
