Any chance you use Virgin Media? Their connection is corrupted, so you will receive this message. If so - wait for it to be fixed
Thanks for replying. I don't know what you mean with 'Virgin Media', but if it is an isp the answer is 'no'. But does your answer imply that the message is caused by a corrupted connection on my part? As I am using a vpn between my isp and the blockchain, does this mean the connection via this vpn provider is corrupted ? What does 'corrupted' mean ? How can I test this ?
[update]After I became unlocked from the newbie forum I made a posting in the proper thread:
