Looks like the cause for issue is your IP changes along the way, the session is started with one IP and then it changes making the session reset causing the login to fail.
I did notice that you are on a mobile connection (at least judging from the look up on the IPs involved), this is unfortunately not an uncommon issue with mobile connections and the log does indicate two IPs (the session file is a mistmatch to the second).
Interestingly though I see you start at one IP and then being rejected on the second with the same IP pairs more then once, which could indicate some kind of proxy being in play, possibly on ISP side as both IPs belong to the same company.
Are you only able to use that mobile connection? Due to the nature it would likely not allow you to login directly to DA either or at least kick you out fairly quick due to IP changing.
