Not sure if this only applies to my issue or larger, but after update to 25.7.1 all working well, I went to recycle strongswan and afterwards the config for all my ipsec tunnels were not reading / showing properly and would not connect. As soon as I reverted back to 25.7 and recycled strongswan again, all appeared correctly and connected. the widget showed no phase 1 when broken on 25.7.1, as it appears to be how it was parsing the config file, it may be larger than just the ipsec issue that I had.
tracking this via https://github.com/opnsense/core/issues/9022 at the moment
can confirm upgrade to 25.7.1 then opnsense-patch b440c12 resolved the issue for me with all my IPSEC tunnels
Thanks for confirming. Hotfix is out as 25.7.1_1.
