UYAP session drops when you sign in from two places at once: exit through the office network with Tailscale

Last updated 10 November 2026

Short answer: If you are signed in to the UYAP Lawyer Portal (Avukat Portalı) at the office and then sign in with the same account from the courthouse, from home or from your phone, the office session may close. The fix is to have every device reach the internet through the office connection: UYAP then sees all sign-ins coming from the same IP address and the earlier session stays open. The simple way to set this up is to make an office computer a Tailscale “exit node” and select that computer on your devices outside the office. Tailscale’s free plan is enough for this.

Why does the session drop?#

The typical situation in a law office: the lawyer signs in to UYAP on the office computer with their e-signature, then signs in again with the same account at the courthouse or at home. When the second sign-in happens, the first session closes. The office screen shows that the session has dropped, and you need to sign in again to continue unfinished work.

The idea: every device exits through the office internet#

If your phone at the courthouse or your computer at home reaches the internet through the office connection, UYAP sees every sign-in coming from the office IP address. There are two ways to do this:

	Tailscale exit node	Static IP and a VPN on the router
What you need	A computer that stays on at the office and a Tailscale account	A static IP from your internet provider and a modem or router that supports VPN
Setup	Installing the app and changing a few settings	Setting up a VPN server on the modem; often needs technical support
Static IP	Not needed; devices use the office’s current IP address	Needed
Cost	The free plan is enough for small offices	Static IP fee, plus equipment and setup if needed

Setting it up with Tailscale#

Tailscale is an app that joins your devices into an encrypted network of their own. When you make one device an “exit node”, the other devices reach the internet through that device’s connection.

Install it on the office computer. On a computer that stays on at the office, download Tailscale from tailscale.com, install it and sign in with an account.
Advertise it as an exit node. On Windows, click the Tailscale icon in the system tray and choose Exit node › Run exit node; on macOS, choose Exit Node › Run Exit Node from the menu bar icon. If you prefer the command line, on Windows type tailscale up --advertise-exit-node in a command prompt opened as administrator.
Approve it in the admin console. In the Tailscale admin console, open the Machines page, click the three dots on the office computer’s row, choose Edit route settings and tick Use as exit node.
Install it on the device outside the office. Install Tailscale on your phone or home computer and sign in with the same account.
Select the exit node. On a phone (iOS and Android), select the office computer in the app’s Exit Node section. On Windows choose Use exit node from the tray icon; on macOS select the office computer under Exit Nodes in the menu bar. On the phone, the VPN icon shows that the connection is on.
Sign in to UYAP as usual. With the connection on, sign in to UYAP with your e-signature. When you are done, turn the exit node off by selecting None.

Points to watch#

The office computer must stay on and awake. If the exit node computer shuts down or goes to sleep, devices outside cannot reach the internet through the office. Turn off sleep; on Windows, turn on Run Unattended so Tailscale keeps running even after you sign out.
Key expiry. By default Tailscale device keys are valid for 180 days; when that period ends, you need to sign in again on the device. For the office computer, you can choose Disable Key Expiry from the menu on the computer’s row on the Machines page of the admin console.
An e-signature is personal. Under Article 4 of the Turkish Electronic Signature Law (No. 5070), a secure electronic signature is created with a tool that is exclusively linked to the signatory and under the signatory’s sole control. This method is for a lawyer signing in to their own account from their own devices; it does not let another person use your e-signature or PIN, and we do not recommend that.
All internet traffic goes through the office. While the exit node is on, all traffic from your phone or computer passes through the office connection; speed is limited by the office’s upload speed. Turn the exit node off when you are done.
Protect your Tailscale account. Anyone who gets into the account can also reach your devices’ network. Turn on two-step verification on the Google or Microsoft account you use for Tailscale.
Plan terms. The free plan currently allows up to six users; check the terms on Tailscale’s pricing page.

Does Yargı PRO solve this?#

No. The session dropping is UYAP’s rule; Yargı PRO cannot change it. Yargı PRO Desktop also signs in to UYAP with your e-signature and is subject to the same rule: when you sign in with the same account from somewhere else, Desktop’s session may drop too, and you can solve it the same way.

Frequently asked questions

Why does my UYAP session drop when I sign in from two places at once?

When the same account signs in a second time, UYAP closes the first session. If you are signed in at the office and sign in with the same account from the courthouse, from home or from your phone, the office session drops and you need to sign in again to continue unfinished work.

How does Tailscale stop the session from dropping?

You install Tailscale on a computer that stays on at the office and make it an exit node; on your phone or computer outside the office you sign in with the same account and select that computer as the exit node. Your devices then reach the internet through the office connection and UYAP sees the sign-ins coming from the same IP address.
