I tried to install Nextcloud per web-installer: https://nextcloud.com/de/install/#community-projects It seems to install all perfectly, but then I cannot login (I can just type in the user and password, click login, then the screen shortly flickers, but nothing happens), but there is also no error message. Afterwards, I tried to install it via Softaculous, but with the same result. Does anyone has the same issues or could imagine what could be the cause?
