Noticed about a week ago that my HSBC connected card was asking me to renew the connection, which was odd as usually I get a warning well in advance of the connection expiring.
Clicked renew, and eventually got to this screen in my HSBC app
Which then took me to this screen in Monzo
Tried uninstalling Monzo, same result. Tried leaving it a week, same result.
Seems most likely to be an HSBC issue, anyone else having a similar issue?
Delete the HSBC app, as the error occurs their side, reinstall and try again.
Just connected my HSBC current account without any issues.
Just tried that, still exact same issue.
I don’t think it’s anything to do with the HSBC app itself, as that wouldn’t cause the Open Banking connection to drop off in the first place.
Monzo AI chat is worse than useless. First recommendation was to remove the HSBC app which would apparently force Monzo to use the browser to reconnect, but that won’t work because without the app you can’t generate a login code for the browser.
Second suggestion was to do it via a desktop…but you can’t do Open Banking stuff via the web interface. 
I had this same problem.
I deleted HSBC,readded, rebooted, etc. No luck.
Monzo support told me that it was an error on the HSBC side that was showing “not eligible” FEC03 (I think).
I called HSBC and they said they couldn’t help with 3rd party app support. I explained this was an error on the HSBC side and they didn’t understand what I was saying and said it was “beyond [their] scope”. They also said that they had upgraded security lately and maybe it was that.
Monzo support did all they could.
My issue has been passed on to the engineering team now, so we’ll see what they say.
If that’s the case though, I’ll have to cancel Extra regardless of whose fault it is as I only have Extra for the connected accounts, and it makes Trends useless without it.
I managed to sort this myself in the end using the following convoluted workaround:
Mine’s now disconnected and won’t reconnect too.
So is this a Monzo or HSBC issue?
It does seem to be a HSBC issue, I get the same thing with open banking in RBS.
Still no idea. Monzo were quick enough to message back saying “Looks like this issue is resolved as you’ve managed to connect the account?”
But then radio silence after I replied saying “No the root issue is still present, but I’ve used a very inconvenient workaround in the meantime”.
It’s a HSBC issue, I get the same error with the RBS and Halifax apps, so hopefully HSBC will fix it their end soon.
I’m working on the basis that it will be fixed before the next account refresh is due anyway, whichever party is responsible🤞
