Error 60 cURL TimeManager


First of all, a happy new year 2021.

I want to install the TimeManager application but an error message appears "cURL error 60: SSL: no alternative certificate subject name matches target host name ‘’ (see /c/libcurl-errors.html)
i tried installing another app i have no problem is it from the source file?

Nextcloud 20.0.4

Thank you in advance for your answers.


the night brings advice, the problem came from PiHole which blocked the installation of the application …

Mea culpa
