Warning when installing/updating themes and plugins

[pavelevap]

There are several problems when trying update/install themes.

Installing themes through Administration does not work. Only following Warning is shown, no theme available:

https://core.trac.wordpress.org/browser/tags/3.9.1/src/wp-admin/includes/theme.php#L350

Installing plugin works without problems.

Updating plugins works, but there are some Warnings in the end of page:

Warning: An unexpected error occurred. Something may be wrong with WordPress.org or this ... in /www/doc/www.activemove.cz/www/wp-includes/update.php on line 119 (and 287, 435).

https://core.trac.wordpress.org/browser/tags/3.9.1/src/wp-includes/update.php#L119

Reinstalling WordPress works without problems (except problem in #28723).

PHP 5.5.14, MySQL 5.5.38, WordPress 3.9.1 (no plugins, Twenty Fourteen). No problem with cURL, etc.

Any idea what should be wrong? Or what should I test?

pavelevap, are you still seeing this?

It has to be related to some kind of server issue. We moved website to another hoster and everything works well now. I am not sure what was wrong, maybe problem with secure connection...
