[Question] Failed to send "count" command with database "dddb": socket error or timeout

[apsbd]

Hi

My server was good until yesterday and now it's showing this error:

Failed to send "count" command with database "dddb": socket error or timeout

at /var/www/html/console/vendor/mongodb/mongodb/src/Operation/Count.php:154
150| if (isset($this->options['readConcern']) && ! \MongoDB\server_supports_feature($server, self::$wireVersionForReadConcern)) {
151| throw UnsupportedException::readConcernNotSupported();
152| }
153|

154| $cursor = $server->executeReadCommand($this->databaseName, new Command($this->createCommandDocument()), $this->createOptions());
155| $result = current($cursor->toArray());
156|
157| // Older server versions may return a float
158| if ( ! isset($result->n) || ! (is_integer($result->n) || is_float($result->n))) {

Exception trace:

1 MongoDB\Driver\Server::executeReadCommand("dddb", Object(MongoDB\Driver\Command), [Object(MongoDB\Driver\ReadPreference)])
/var/www/html/console/vendor/mongodb/mongodb/src/Operation/Count.php:154

2 MongoDB\Operation\Count::execute(Object(MongoDB\Driver\Server))
/var/www/html/console/vendor/mongodb/mongodb/src/Collection.php:277

Please use the argument -v to see more details.

It would be really very helpful if you give me a solution.

Thanks in advance

@apsbd Failed to send "count" command with database "dddb": socket error or timeout looks like connect error

I have same similar issue with the count() timeout

While looking at mongo docs I noticed this note

MongoDB drivers compatible with the 4.0 features deprecate their respective cursor and collection count() APIs in favor of new APIs for countDocuments() and estimatedDocumentCount(). For the specific API names for a given driver, see the driver documentation.

How can I call countDocuments() or estimatedDocumentCount() methods with this library?
