Inappropriate handling of SocketTimeOutException

[kleinmind]

Every now and then, the fetching fails due to a SocketTimeoutException (see in detail below). This can be better handled, e.g. when detected, the fetcher could retry the download after some time (maybe a max number of retries should be set).

Detailed log of exception:
