Hi,

the following URL shows the issue here: https://curl.haxx.se/libcurl/c/libcurl-errors.html

CURLE_SSL_CONNECT_ERROR (35)
A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.

Most likely caused by some environmental issues / bugs in your used OpenSSL library or similar. If you can't fix your environment to do a correct SSL connection just do the manual update.

Can you tell me what file in OC or updater that contains the code for executing a curl request so I can log what is going on?

https://github.com/owncloud/updater/search?utf8=%E2%9C%93&q=curl

shows some sources where curl might be used.

Thanks for the help!! Might have an easier way to figure out what is going on. Do you know what URL the updater is using? Is it simply https://download.owncloud.org/community/owncloud-9.1.1.tar.bz2? Thought about just doing a curl request myself to see if I get any errors?

https://updates.owncloud.com/server/ and https://download.owncloud.org/community/owncloud-9.1.1.zip

updater relies guzzle client for requests: https://github.com/owncloud/updater/tree/c43e2f8640c1cf8b5228b182892d46e6f0b66bc4/vendor/guzzlehttp/guzzle
