Short answers to the questions support hears most often. If your case is not here, write in "My account → Support" and attach the diagnostics report — "Settings → Updates → Diagnostics → Copy report".
Running tasks
The start button is inactive
The reason is always written in yellow above the button in the "Launch" block: no accounts chosen, no post text, no AI key, the browser is not ready or the module is not in the license. Fix what it says — the button becomes active.
A task ended "Partial" or with errors
Open "Task logs" → the eye button of the task. The task window says for each account what worked and what did not. Common reasons: the account needs verification, the proxy did not answer, or Threads did not confirm the action.
A scheduled run was missed
A schedule works only while the computer is on and Thredium is open. If the computer slept or the app was closed, the run is missed and an "A scheduled run was missed" notification comes. Turn on "Settings → General → Keep the computer awake while tasks run" and set a new time. Closing the laptop lid still puts the computer to sleep.
The computer slows down, browser tabs crash
Too many browsers at once for this computer. Reduce "Max workers" in "Settings → General" to the recommended value — it is written under the field.
Accounts and sign-in
"Password not accepted" though the password is right
Threads answers the same when the sign-in goes through a bad proxy. If the password is surely right, give the account another proxy and check it again. If many accounts on one proxy show this, the proxy is to blame.
Threads asked for a verification
The account has the "Needs verification" status. Press "⋯" → "Manual login", pass the check in the window that opens and close it. The 2FA code can be copied with the key button in the 2FA column.
The browser did not finish starting, or Camoufox closed
Check this account again. If the error repeats for every account, restart Thredium. If that does not help, install the latest version in "Settings → Updates".
Proxies
All proxies became unavailable at once
Most often this is an outage at the proxy provider, not in Thredium. If the reason says "Check proxy credentials", check the login and password in the provider's cabinet and its status page. When the provider works again, press "Check all".
Accounts stop with an error on a mobile proxy
A mobile proxy is slow, and with 3–4 accounts at once the actions are not confirmed in time. Set "Settings → General → At once on one proxy" to 1–2.
An "Unstable" proxy
Most accounts on this proxy got a ban or a checkpoint in 7 days. Replace the proxy and hand its accounts out to others — the "Proxies" section, "Distribute".
AI commenting
Few comments or none at all
If languages are chosen in "Reply languages", the accounts comment only on posts in these languages. If the feed has few such posts, there are few comments. Add interests in the language you need or clear the language choice. Also check "Minimum comments under post" — a high value filters out almost every post.
An AI key error
Check the key in "Settings → AI models" and run "Test AI comment" on the AI commenting page. If the provider reports a limit or overload, wait or choose another provider.
License and payment
The license does not activate on a new computer
A license has a limited number of devices. Unlink the old computer in "My account → Devices" and activate again.
I paid a top-up but the balance did not change
The money arrives after Heleket confirms the payment. Check "My account → Balance": a paid invoice disappears from "Unpaid invoices", and the top-up appears in "Balance history". If the payment went through but the top-up does not arrive for a long time, write to support with the amount and the time of payment.
Installation
The system does not let the installer run
On Windows, in the protection window press "More info" → "Run anyway". On macOS open "System Settings" → "Privacy & Security" → "Open Anyway".
