Hello,

Translation: 217.12.253.226 does not know anything about 83.234.107.110.
Please post here the following output FROM 217.12.253.226 , sanitized if You care:
show configuration security ike | display set | match 83.234.107.110 | no-more
If there is an output, then "restart ipsec-key-management" on 217.12.253.226 could help.
Another but rare possibility is that You may have duplicate IPs in Your network.
