MELCloud linked to Mitsubishi Ecodan air source heat pump lost internet connection- Won't re-connect?

I have MELCloud linked to my Mitubishi Ecodan air source heat pump.
Recently I lost the internet connection and cannot establish a reconnection.
My connection is via Access mode as my router does not have a WPS button.
I am able to complete the process for reconnection correctly but it does not connect.
I have previously been successful and there are no changes to my home network settings.
I am wondering if;
the MELCoud server is down?
or if I have a non standard password to my home wifi network - it includes a ’ and has a space in it?
Any help with reconnecting to the internet would be useful.

    It seems to be a wider issue as there’s an update on the support page. 
     

    not sure I believe the ‘relatively small’ numbers affected. 
     

    I can’t find anyway to submit a support ticket.

      Hello all,

      thank for your answers, let me share with you the following:

      1. On Monday the MelCloud support wrote me that no issues are known at their cloud service side. They were giving me long troubleshooting steps to do
      2. I did something different faster and easier not mentioned by Mitsubishi Support: power off the electricity in all my house for a minute and on again.
      3.  I was happy as it was SOLVED
      4. Last night I received again mail notification by MelCloud mentioning same communication error
      5. I check the app and this time is slightly different the issue: one unit it’s OK, the other unit shows same issue as days ago
      6. Checking my FritzBox 7590 router I can confirm (just like last time) that both the units look like perfectly connected to Wifi 2.4 with 72Mb bandwidth, perfect as always since years
      7. I strongly suspect that this random communication issue with MELCloud could be caused by something brought in by the FritzOS 7.50 because with 7.29 I never had any communication issue on the wifi network with any device in the Mesh network. Nothing else at all have been changed so far, everything else is exactly as it was like since years. 
         
      8. so now I’d love to know from any of you guys if you are using FritzOS 7.50. In the meantime I will power cycle again and I am sure it will solve.
      9.  I don’t think it’s an hardware issue because at the beginning of this story the issue was on both the Wifi units, smell very strange to be suddenly hardware issue on 2/2 from nothing.. right?
      10.  I will inform also the support MelCloud for them to be aware and investigate internally within their engineering team and FritzOS team too. Will keep you posted, thank you, regards

      I hate to depend on cloud to control the AC. I tried to put the IP of the AC in the browser just to see if there's any local lan control menu and It requests user/pass, dos anyone know how to get that credentials or any other way to control this in local lan? Thanks

      According to Home Assistant, MELCloud supports Cloud Polling only. There is no known local interface i.e. their stuff only communicates directly with MELCloud itself.
