Hello,
first of all, can you provide your company name, so we would check the server, did it update properly or not.
1. when you updated the server, was it running properly, HDB correct size, as it was before?
2. if the server was running, and HDb was correct, how did you do step 3 ? Did you try to use mystandard, and "connect" >> download client?
Firstly check these two options, to find out is your server running properly. If so, then you should be able to connect to it with downloaded client from mystandard.
We don't want to mix things up for you with local servers, so please confirm above.
Initialy, on mystandard update is done in this sequence:
1. Stop server, and push create backup.
2. When backup is finished, you can double check in "File manager" >> Backup folder, that you can see the proper backup, with todays date. TB180802.txt
3. Click update version, specify available cache, and version you want to update to. Push Update.
4. After update check server HDB is similar size as in 8.1.
5. Try to connect with your current client's to server. The clients shouls say please update client, click update.
6. If autoupdate fails, you can't connect, in mystandard, click on Connect>>download client - this will download new 8.4 client, install it, and it should connect straight to the server.
