got the error below from one of my spoke for site-to-site VPN. my topology is hub and spoke, site-to-site VPNs to other spoke are up only to this particular spoke VPN is down. note that my MX64 connects directly to my ISP, and i'm using the same ISP on all my spoke and hub. the site-to-site VPN used to work but then suddenly went down. no configurations changes are made. does anyone experience this before? any solution tip is much appreciated. really need help on this.
