A one-off disconnection is routine. One every few days means something is triggering LinkedIn’s security checks repeatedly.
Causes, in order of likelihood
1. Inconsistent access locations. The account is being used from places that do not fit together: you in one country, the profile owner in another, plus automation from somewhere else again. LinkedIn treats this as a possible compromise and issues a checkpoint.
Fix: keep each account’s access pattern consistent. See running multiple accounts.
2. A second tool on the same profile. Another automation tool, or a browser extension still installed and active, acting on the same account.
Fix: remove other tools and extensions from that profile entirely. Two tools on one account is also how daily limits get exceeded without either tool knowing.
3. Frequent password changes. Every change invalidates the session.
Fix: settle on a password and, if several people need the account, use a shared password manager rather than rotating it.
4. Two-factor prompts not completed. If 2FA challenges regularly and nobody completes them, the connection keeps dropping.
Fix: have the profile owner complete the challenge once from their usual device.
5. The account is being restricted. Repeated disconnection alongside verification prompts can be an early restriction signal rather than a connection issue.
Fix: check account health and treat it as a risk signal, reducing volume rather than just reconnecting again.
Diagnosing
Look at the account’s activity log for the disconnection timestamps. If they cluster right after a login from an unusual place, cause 1. If they follow campaign bursts, look at cause 5.
If it keeps happening after all of this, send us the account name and rough timestamps and we will check the connection logs.
