Problem: An error occurred while trying to access the service
On January 29, 2018, Adobe disabled Transport Layer Security (TLS) 1.0/1.1 on the server-end for Document Cloud services, such as Create PDF, Export PDF, Send & Track, and so on. As a result, if your browser is configured to use TLS 1.0/1.1, you will see the following error message while accessing the services: "An error occurred while trying to access the service."
Recommendations to the users
- If you’re using Acrobat 11.x or Reader 11.x, upgrade to Acrobat or Acrobat Reader.
- If you’re using Internet Explorer (IE) 8, 9, or 10, enable TLS 1.2 in IE. (Alternatively, you can use IE 11 as it has TLS 1.2 enabled by default.)
- If you're using Adobe Acrobat Reader mobile app on Android, update the app to the latest version from the Google Play store.
Solution: Enable TLS 1.2 in IE
Scroll down to Security settings, and then select the Use TLS 1.2 checkbox.Pastaba:
If TLS settings are enforced using GPO, then these options may appear as disabled. Contact your organization's IT support for enabling the TLS 1.2 setting.
You can enable support for the TLS 1.2 protocol in Internet Explorer using Group Policy by modifying the Turn Off Encryption Support Group Policy Object.
Open Group Policy Management: Press Window + R keys, type MMC in the Open box and then click OK.
Select the group policy object to modify, right-click, and then select Edit.
In the Group Policy Management Editor, browse to the following setting:
Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Advanced Page > Turn off encryption support.
Double-click the Turn off Encryption Support setting to edit it.
In the Options window, change the Secure Protocol combinations setting to a setting which includes TLS 1.2, most commonly "Use TLS 1.0, TLS 1.1 and TLS 1.2".Pastaba:
It is important to check consecutive versions. Not selecting consecutive versions (for example, checking TLS 1.0 and 1.2, but not checking 1.1) could result in connection errors.
