First check if the table exists in your database. If not, you should try to run the following occ commands to fix/repair your installation:

maintenance:repair          repair this installation

db:add-missing-indices      Add missing indices to the database tables
db:add-missing-columns      Add missing optional columns to the database tables
db:add-missing-primary-keys Add missing primary keys to the database tables.

If you still run into that error, try to create the table manually and re-run the above commands.

OK, I checked
# mysqlcheck -c -u root -p --all-databases

and result

nextcloud.oc_file_locks
Error : Table ‘nextcloud.oc_file_locks’ doesn’t exist
status : Operation failed
mysqlcheck: Got error: 2013: Lost connection to MySQL server during query when executing 'CHECK TABLE … ’

after
use nextcloud;
show tables;

…
| oc_federated_reshares |
| oc_file_locks |
| oc_filecache |
…
desc oc_file_locks;

I get answer

mysql> desc oc_file_locks;

In this case you definitely have a problem with your database server. You should investigate further why the server connection get lost or the database becomes unresponsive.

OK, I have solution for my problem. I downloaded WinSCP, loged in to my server and found path to my data. /mnt/nashome/iocage/jails/nextcloud/root/usr/local/www/nextcloud/data/admin/files/ and download. After that reinstal nextcloud.
