Web interface won't load

Update. After working through the command line user guide to try and fix a Wiring error (setting it to MINI_V2), it fixed that, which was preventing start up, also the touch on the touchscreen that wasn’t working since rebuild, and now (venv) appears at command line too, so not really sure what happened there, but maybe some bits weren’t firing up before. Now the touchscreen is plugged in again, the delay in the web interface load is back - here’s the journalctl output at the time

Back in March I gave up on trying to fix this issue with no further input to explore. But I just installed a new image, with oram-2511.3, and still have this problem - sometimes the web ui is slow to open, sometimes it won’t load at all. Just now it was slow, but then loaded. The log shows

any clues on why there might be a 2 min wait - is something else locking it out for which it needs to wait?
