Hi all, I bumped into the same issue, and luckily the support helped me (many thanks). Let me describe the problem and the solution.
Environment: Ubuntu 22.04 LTS, Installation along the guidelines provided in:
a.) Same issue as above, Error “download failed”. This only happened to me, when ssl was on, it worked ok with http:// only. Verification was done just on the examples page /example
b.) I used a self signed certificate (which also seemed to be important, as naturally certificate verfication fails)
b.1) The doc service log : /var/log/onlyoffice/documentserver/docservice/out.log shows the following error:
[2023-01-30T09:05:00.090] [ERROR] [localhost] [172.30.41.23Test.xlsx1674744767521] [uid-11] nodeJS - changesError: Error: Uncaught TypeError: Cannot read properties of null (reading 'Tsj') Script: http://onlyoffice.mydomain.com/7.2.2-56/sdkjs/cell/sdk-all-min.js Line: 1530:320 userAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.96.36.199 Safari/537.36 platform: Win32 isLoadFullApi: false isDocumentLoadComplete: false StackTrace: TypeError: Cannot read properties of null (reading 'Tsj') at Sb.N$g (http://onlyoffice.mydomain.com/7.2.2-56/sdkjs/cell/sdk-all-min.js:1530:320)

As could not find any reasonable comments in the public, I contacted the support, and their recommendation was:
a.) Switch off ssl verification in /etc/onlyoffice/documentserver/default.json, i.e. search for entry “rejectUnauthorized”, change the value from true to false and restart the services by using:
sudo supervisorctl restart all
On my end, this did not help, I still had an the permission issue as before. Only after running the command (as described here as well):
sudo documentserver-update-securelink.sh things went ok.
I do assume that self signing is key for this error, as I ran OO in a very similar environment on debian with a letsencrypt certificate and never had any such issue
Thanks for the great help of the support.
Hope this helps to save some time for others.
