Why the login Facebook stored stops counting, which checks to run in what order, and what you can control on the proxy side.
1. The cookies are gone. Chrome's help says that deleting cookies may sign you out of sites that remember you. A cookie cleaner, a privacy extension, or a browser profile that does not keep its data between sessions has the same effect, and it looks like “session expired” on the next visit.
2. The session was ended. Facebook lists every login under Password and security, in the Where you're logged in section, with date, time, location and device type. Selecting a session and choosing Log out ends it immediately on that device. You, a teammate who has the password, or someone else can end a session this way.
3. The connection changed under the session. A rotating proxy gives a new exit IP for each new connection, so the location Facebook sees can change in the middle of one login. Facebook does not document what ends a session, but this is the part you can remove: use one static IP for the account.
| Item | Likely cause | What to check |
|---|---|---|
| Logged out every time the browser closes | Cookies are deleted on close, by a setting or an extension | Browser cookie settings; test in a private window with extensions off |
| Logged out after minutes or hours | The proxy exit changes, or the session was ended elsewhere | Run ipinfo.io through the proxy twice; open Where you're logged in |
| Logged out on every device at once | Sessions were ended in Password and security, or the password changed | Check Where you're logged in; if it was not you, use facebook.com/hacked on a device you used before |
| Login loop or a request to confirm it's you | Facebook wants more proof before it keeps the session | Complete what Facebook asks honestly; check the IP and the proxy settings; ticket with us if the IP itself fails |
Source: Facebook Help Center pages “Log out of Facebook on another device” and “Recover a hacked account”, and Chrome Help, read 15 November 2026. Facebook does not publish a full list of reasons a session ends.
Open Password and security and then Where you're logged in. Each entry shows date, time, location and device type. If you see sessions you do not know, go to facebook.com/hacked on a device you have used before. If they are all yours, continue.
Open Facebook in a window with extensions off. If the session now lasts, turn extensions back on one at a time; cookie cleaners and privacy tools are the usual suspects.
Check that nothing deletes cookies automatically. If you use a separate browser profile for each account, check that the profile saves its data between launches. Chrome warns that deleting cookies can sign you out of sites that remember you.
Run the curl loop below. The same IP both times means a static exit; two different IPs mean the exit rotates, which is not what you want for a logged-in account.
Expected result The same IP twice for a static IP.
Chrome and Edge do not support SOCKS5 with a username and password, so for a browser use an HTTP asset (port 2222). If the browser asks for the proxy login again and again, see the proxy authentication guide.
Sign in on the IP you use for this account and finish any check Facebook shows. Do not open the same account from several IPs at the same time, and do not share the password: Facebook's terms say you must not.
Before continuing Do not log the account in and out repeatedly from different IPs to see which one holds.
# Run twice, a minute apart: is the exit IP the same?
for i in 1 2; do curl -s -x http://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/ip; echo; sleep 60; done
# SOCKS5 asset (port 3333)
curl -s -x socks5h://LOGIN:PASSWORD@HOST:PORT https://ipinfo.io/jsonExample only: replace LOGIN, PASSWORD, HOST and PORT with the values from My assets.
Check Cookie settings and extensions; does the same happen in a private window with extensions off?
Fix Allow Facebook's cookies to stay, and remove or reconfigure the cleaner.
Stop when If a private window with extensions off also logs you out, the proxy is not the cause.
Check The curl loop above.
Fix Use a static ISP IP, or a fixed session if you use a rotating line, for this account.
Stop when Do not keep signing in while the IP keeps changing.
Check Where you're logged in, and the recover-a-hacked-account page.
Fix Follow Facebook's recovery steps from a device you have used before.
Stop when Do not keep using the account through the proxy until you are sure it is yours alone.
Check The proxy fails before Facebook is reached.
Fix Follow the proxy address and port guide.
Stop when If curl also fails, send a ticket with the order number.
A proxy changes the address Facebook sees. It does not change Facebook's decisions about an account. The terms say you must provide accurate information, create only one account of your own and not share your password or give others access to it, and they do not allow collecting data from Facebook with automated means without permission.
We do not claim that a static IP stops logouts or security checks. It removes one cause you control, which is an exit that changes between requests. For several people on one Page, use the access options Facebook provides.
For an account you log in to every day, a static ISP IP is the usual fit: it stays the same for the whole lease. One IP costs US$0.50 for 1 day or US$7.99 for 30 days (about US$0.27 a day, 7.99 ÷ 30), the same in every country. There is no free trial, and stock for each country is shown on the order page.
The Facebook use-case page covers the full setup.
Open the static ISP page, choose the country and the term, keep the protocol on HTTP for a browser, and pay from the wallet.
Open My assets and copy HOST, PORT, USERNAME and PASSWORD. HTTP uses port 2222 and SOCKS5 uses port 3333 on proxy.proxy302.com.
Enter them in the browser profile you use for this Facebook account only.
Open https://ipinfo.io/json through the proxy to confirm the country, then sign in.
The stored login no longer counts: the cookie was deleted, the session was ended in Password and security, or the browser did not send it. Facebook does not publish a full list of reasons, so work through the checks above.
Not by itself. A working proxy that keeps the same exit leaves your cookies alone. Typical triggers are cleared cookies, wrong proxy settings, or an exit that changes between requests.
Only Facebook's, not everything. Chrome warns that deleting cookies can sign you out of other sites that remember you.
Facebook's terms say you must not share your password or give others access to your account. For one account, use one IP; for a team, use the access options Facebook offers.
Facebook reads your IP at every login; this guide explains what it can see, why location jumps trigger checks, and why a long-lived account suits a static IP.
The ERR_PROXY_CONNECTION_FAILED error appears in Chrome and Edge when the browser cannot establish a connection with a proxy server.
Check the exit IP, country and ISP your proxy really gives you in 30 seconds — and why IP databases disagree on the city. With our own test of three lookup services.
Fixed static ISP proxies: a residential-grade IP that stays the same for the whole term. For social accounts, stores and AI tools. HTTP and SOCKS5.
