Why a tool keeps asking you to reconnect your account

Short answer. Most of the time this is not a failure of the tool. Access to your account is granted by the platform for a limited period and revoked under the platform's own rules — sometimes after an hour, sometimes after a password change, sometimes with no explanation.

*Checked 28 July 2026. Every statement links to the platforms' documentation or to a vendor's own page.*

Reason 1. The access token lives for an hour

VKontakte has three kinds of token, and their lifetimes differ:

Hence the practical consequence: a tool that acts on your behalf has to refresh the token. If it does not, or the refresh fails, scheduled posts will not go out — and you will be asked to connect again.

What to do. Where you can, connect a community or page rather than a personal profile: their tokens do not expire.

Reason 2. The platform revoked permissions

Buffer on TikTok: the account is disconnected "when TikTok revokes or expires publishing permissions, such as after security or account changes". source

In other words, a password change, turning on two-factor protection, or changing the account type can silently break the connection. The tool finds out only when it tries to publish.

Reason 3. The API version changed

LinkedIn requires every request to carry a version in YYYYMM format. source

The version rolls forward on a calendar schedule. A tool that does not keep up one day stops working — not because it "broke", but because its version is out of date.

This is worth knowing when choosing: supporting LinkedIn takes continuous maintenance, and an abandoned tool will drop out on its own.

Reason 4. The platform changes the rules

VKontakte, 2 April 2026: integrations must use only the methods from the official documentation; unpublished methods will be restricted in stages. source

And separately: the platform is entitled to terminate an application's access without notice, in whole or in part. source

A tool that has been working through undocumented methods may disappear for you on any given day. And not one of the twelve tools checked states on its site that it works officially — you cannot verify this from their pages.
