Octo Browser Failed to Get Proxy Data: Fix
What to check when an Octo Browser proxy shows red or Unavailable, or a profile will not start through its proxy.
The 3 most common causes
1. The protocol does not match the IP, or the pasted line split wrongly. Octo reads protocol://login:password@host:port and host:port:login:password from the Host field; without a protocol in the line, the dropdown on the left decides.
2. The IP has expired, or it carries usage restrictions. The docs advise against restricted proxies because the check can fail when a profile starts.
3. The check cannot reach the proxy from your network. The default check timeout is 5 seconds, and the docs say that a working proxy can fail the check when the internet provider blocks the checker address.
Six checks, in order
Step 1: Paste the whole line into Host
In My proxies and VPNs click New proxy / VPN and paste the full line into the Host field so protocol, host, port, login and password split into their boxes. Compare each box with My assets.
Step 2: Match the protocol
If the line has no protocol in front, set the dropdown to the protocol My assets shows for the IP: SOCKS5 or HTTP. Octo recommends SOCKS5 or SSH; a Proxy302 IP can be generated as SOCKS5.
Step 3: Click Check proxy and read the result
A green Available with a flag means the proxy works. A red Unavailable means the check failed. In the list, gray means not checked or checked more than 5 minutes ago, so check again.
Step 4: Check the end date
Open the IP in My assets and read the end date. If it expired, renew it or buy a new one and replace the saved proxy. Auto-renew is optional and set per IP.
Step 5: Test from another network
If the proxy works elsewhere but fails the check, try a phone hotspot or another connection and check again. The docs give this as the fix when the provider blocks the checker URL.
Step 6: Test outside Octo with curl
Run the commands below. If curl returns the exit IP, the proxy works and the issue is in the settings or the network of the check. If curl times out or returns 407, see the table.
Symptom, check, action
Works in curl, Unavailable in Octo
Check Your internet provider may block the checker address.
Fix Check from a phone hotspot or another connection.
Gray status
Check The proxy was not checked, or the last check is older than 5 minutes.
Fix Click Check proxy again.
Connection error while a profile is open
Check The proxy stopped working mid-session.
Fix Close the profile, check the end date, replace the proxy, save, and restart the profile.
Stop when If a new IP fails the same way, open a ticket with the order number.
Question mark instead of a flag
Check Octo could not determine the country from the IP.
Fix Check again; compare the exit IP with My assets.
What the two tests tell you together
| Item | curl test | Most likely cause |
|---|---|---|
| Check proxy: Unavailable | Fails | Address, port, credentials, expiry or your network |
| Check proxy: Unavailable | Works | Octo settings (protocol, the split line) or a network that blocks the checker |
| Check proxy: Available, profile errors later | Works | The proxy stopped mid-session: check the end date |
| Both pass, wrong country | Works | A different proxy is selected in the profile |
Combination of the two tests; statuses, the 5-second default and the checker-blocking note are from the Octo Browser docs read on 14 November 2026.
Test the same proxy with curl
# HTTP IP (port 2222)
curl -x http://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/json
# SOCKS5 IP (port 3333); socks5h also resolves DNS through the proxy
curl -x socks5h://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/jsonExample only: replace LOGIN, PASSWORD, HOST and PORT with the values from My assets.
What the documentation does not say
We could not find the exact text "failed to get proxy data" in the Octo Browser documentation, so this guide does not claim to quote it. The statuses and causes above are the ones the documentation states. If your Octo version shows different wording, the same checks apply.
A passing check shows only that the proxy connects. Platform rules are separate: use each account as the platform allows, from an IP in the account's country.
How to do it with Proxy302
Octo Browser keeps the proxies you buy yourself in its Proxy Manager. For accounts you keep for months, give each profile its own static ISP IP: from US$0.50 for 1 day to US$7.99 for 30 days, the same in every country. Screenshots and bulk import are on the Octo Browser page.
How to do it with Proxy302: steps
Step 1
Open the IP in My assets, note the protocol tag and click host:port:user:pass to copy the line.
Step 2
In Octo Browser open My proxies and VPNs, click New proxy / VPN and paste the line into Host.
Step 3
Set the protocol if the line has none, click Check proxy and confirm.
Step 4
In the profile list pick the saved proxy in the Proxy / VPN column and confirm the exit with an IP checker.
FAQ
What does "failed to get proxy data" mean in Octo Browser?
The documentation does not use this wording. Read it as the proxy check failing: look at the status colour, the Unavailable result, the protocol and the end date of the IP.
Which formats can I paste into the Host field?
protocol://login:password@host:port or host:port:login:password. Octo splits the line into the boxes.
Why does Check proxy say Unavailable when curl works?
The docs say a working proxy can fail the check when the internet provider blocks the checker address. Try a phone hotspot or another connection.
Which protocol should I pick for a Proxy302 IP?
The one My assets shows for that IP. Octo recommends SOCKS5 or SSH, and a Proxy302 IP can be generated as SOCKS5, port 3333.
How do I replace a failed proxy on a profile?
Close the profile, pick the new proxy in the Proxy / VPN column, save, and start the profile again. Octo applies changes after saving and restarting.
